We have a number of water bottles in our house. Over time, more are acquired and more are lost, but we have certainly gone through plenty as a household. This particular water bottle is ergonomic and designed to keep your liquid cool through an innovative ice tube. It's a 500ml bottle but is also available in a slightly larger 700ml size.
While the ice tube is certainly its unique selling point, the ergonomic design is one of the first things you notice in a positive way. It fits very comfortably in the hand and doesn't feel as if it's going to slide out and be dropped at any point. This makes it quite handy for exercise, particularly when you have sweaty hands or you're out running in the rain.
The bottle has a screw top, but inside it's slightly more complicated due to the unique interior. There is a flip top lid which seals itself closed once the lid is screwed on, but the central insert means that this isn't a simple screw top and nothing else. Inside, there is a section across the top which has a slot in it. A separate hard plastic tube can be removed, filled with water and frozen before then being returned into the slot, where it sinks down into the bottle and fits snugly across the top. The sealed flap and the screw top lid complete the design.
In cold weather, I wouldn't bother with the central plastic section. Although it's not that thick, it does take up room and the more empty the bottle gets then the more you notice a slight difference in weight distribution. However, it doesn't rattle around or anything. The only slight issue is that occasionally it can leak a few drops and this can come out from the flip top element on top of the screw top lid - its seal isn't the best. If I'm running and open it to take a drink then my hands can get wet - in windy but dry conditions this makes my hands cold, whether or not I've use the frozen core, so it's bit annoying. I know a couple of people who have this design though and they say they haven't experienced any leakage, so it's entirely possible that it may just be the particular one I have.
For use in the gym though it's ideal, and the best bit is how the frozen core really does keep the drink nice and cold. It makes a difference from water that's going slightly warm because it has been in the bottle for a long time in my bag, for example. As a unique selling point it really does the job - I find that in hot situations you can't beat something that's cool as well as refreshing.
It's also easy to clean. We don't have a dishwasher (although it's dishwasher proof) and it can sometimes be really hard to wash the inside of a water bottle. Smells linger from previous drinks and staining often happen. This bottle doesn't keep lingering smells or stains though - it just washes and smells like a new and clean bottle.
All in all then, a recommended water bottle. Fits well in your hand, has a great unique central frozen tube for keeping your contents chilled, and washes easily. Occasional leakage may well be down to the individual bottle, but it's still slightly annoying, as is the tube if you're not using it or if the bottle gets empty. Recommended, just not perfect.
My Daughter likes to take a drink to school with her each day. She usually refilled an old 500ml pop bottle or brought a new drink from the shop each morning on the way to school. I find both ways unsatisfactory as refilling a previously used disposable pop bottle is unhygienic and buying a new bottle of pop five days a week is costly. Then she started 'borrowing' my Husbands sports bottle that he uses for the gym each morning, not a very good solution as my Husband would have to hunt the bottle down when he wanted it and my daughter would have to do the same when she wanted it.
After a week of bottle hunting and borrowing my Husband had had enough and ordered our daughter a nice girly pink bottle from amazon.co.uk, the cost of this bottle was £4.99, equivalent to a weeks worth of pop from the shop.
When the bottle arrived I was impressed to see that the bottle was a Thermos branded sports bottle or to give it its proper title Thermos Hydro Sports Bottle with Ice Tube. The bottle is available in Blue (manly) Charcoal (unisex) Pink (girly) and maybe a few other colours.
I was intrigued by the ice tube idea, after a few minutes investigation I discovered that the 'Ice Tube' was a refillable plastic tube. To use the 'Ice Tube' all you need to do was fill the tube to the water line, screw the lid back on and then place it in the freezer. When the 'Ice Tube' has frozen it can then be placed in the drinks bottle. This will then keep your water or juice nicely chilled. I think this a great idea for warmer months as it will keep my Daughters drink chilled throughout part of the day at school.
When I gave the bottle a closer inspection I was impressed to see that Thermos have fitted rubber seals in all the right places, I know this sounds strange but bottles lacking in seals have resulted in soaking my daughters school bag and its contents on more than one occasion.
The lid is nicely domed and has a 'rapid flow' spout for easy drinking. I have tried this bottle out for review purposes and can report that my water flowed from the bottle at a good rate. The oval shape of the opening contours nicely with my lips. When the cap of the spout is flipped open it can be pushed back a little further where it will lock into place, this is great as it stops the cap from trying to flip closed while drinking. The hinge of the spout cap looks well made and does not stand too proud of the lid itself. I think this positioning will protect the hinges from being accidentally damaged while in my Daughters bag or when being carried about.
The lid of the bottle is accented with black rubber, not only does this look great but it provides grip when opening and closing the lid. The body of the bottle is nicely shaped and is again accented with black rubber, in this case it provides a good gripping point for your hand, ensuring that if your hands are wet and sweaty or the bottle is wet that it will not easily slip from your grip.
The sports bottle can comfortably hold 450ml of liquid (non carbonated beverages and cold beverages only) and this is indicated by the measure up one side of the bottle in ml indicating 250ml, 350ml and 450ml. The bottle also measures in fluid ounces and is indicated at 9floz, 12floz and 15floz.This is handy if you are monitoring your fluid intake levels.
My Daughter has been using this bottle for a couple of weeks now and it still looks in good condition, there are a few slight scratches on the outer of the bottle but nothing major. I think the bottle is a sound investment as it costs the equivalent of buying a weeks pop from the shop, any use after a week is a financial saving which really adds up when watching the pennies. I also feel this bottle is a lot better than refilling disposable pop bottles as it is very easy to dismantle and give a good wash out each day. My Husband was so impressed with the look and feel of the Thermos Hydro Active Sports Bottle with Ice Tube that he ordered a second one in blue for himself.

Thank you for reading.
For a long time I would simply refill an old water/coke bottle with some juice to put into my lunchbox for work however, some of these bottles were starting to look at little worse for wear, and when I noticed TK Maxx selling these Thermos Hydro Sports Bottles for £4.99 I thought it was the right time to buy one. I actually bought my bottle in pink, because TK Maxx were only selling that colour at the time, however I do believe there are a variety of colours for this product.
Thermos is a recognised name so I was confident in the effectiveness of this product. My bottle has a 450ml capacity, which is ample for my lunchbox or if you are going out for the day. I took this bottle on our recent holiday and filled it everyday, and found it to offer enough to drink throughout the day.
This flask also claims to be free from BPA which I like. It is only suitable for non carbonated drinks, which may be a hindrance to some people, but is ideal for me as I only ever put water or diluted juice in my bottle. This bottle is also dishwasher safe - we don't have a dishwasher but I have found the bottle to be easy to wash out and it drys quickly.
Probably the feature that most attracted me to this product was the refillable ice tube that you can chose to insert into your bottle after having froze it beforehand. Now, with the early summer weather, even when we were away on holiday, there wasn't much need for me to add the ice tube to my bottle, but with the better weather last week, I got a chance to try it out, and I was very pleased with the outcome. The ice tube which was easily inserted into the bottle did keep my drink cool for a good part of the day, so this is a big plus if you are likely to be somewhere with a lot of good weather. No one likes there water to go warm in the heat and my husband was rather envious when I showed him this bottle, as his work bottle only holds liquid and has no ice tube facility.
When I was thinking about buying this product, the only slight concern I had was the lid at the top of the bottle didn't feel that secure when I closed it, and I honestly wondered if this bottle would be one that easily leaked. However, I decided to take the chance given that Thermos claim this bottle is spill resistant. Now when you are actually using the bottle, the lid is a lot tighter when you close it than it looks, and when we were away on holiday, my little girl managed to grab this bottle sometimes to play with and never once did she manage to spill this, or in fact get the lid open.
The final feature of this bottle which I think is good is that it has a rapid flow lid, so it isn;t the kind of bottle that you have to suck liquid out of, meaning if you are desperate for a drink, the opening of the bottle is wide enough so you take a good drink out of it to quench your thirst quickly rather than some token sips. I find this particularly useful if I have been out and walk and desperately need a drink, I can take a good amount quickly and feel refreshed very quickly.
All in all, this is a great bottle, and I have been very impressed so far. It hasn't leaked, it keeps my drinks cool and even cooler when I add the ice tube, it has a good opening, and I like the fact it is BPA free.
I've owned more sports bottles over the years than I care to remember - probably because I buy whatever's cheap in the shops, and don't perform extensive research into which bottles are actually any good. In my collection are two Thermos 'Hydro' bottles - one of which I was given free, and the other cost me £4 on the high street. When I think of the brand Thermos, my mind turns to products which are designed to keep liquids warm - but the Hydro is designed to do the exact opposite. It features a plastic core which can be filled with liquid and then frozen - hence keeping the remainder of the fluids cool.
Design & Performance
- - - - - - - - - - - - - -
Constructed from a sturdy plastic, the Thermos Hydro has a 500ml capacity and is dishwasher safe. The bottle can be filled via an easy-open screw top, but the actual drinking mechanism is a little different - it takes the form of a flap which lifts and closes with little effort. Said flap has a plastic seal which in theory should stop any leaking - but does it work?
So let's take a look at the good and the bad in terms of the bottle's performance, starting with the positives. Firstly, the Thermos is comfortable to hold, and its shape is conducive to not slipping out of the hand. The second good point (and this one's really important in terms of a bottle's overall rating) is the fact that it doesn't absorb the aroma of the liquid which it previously held. The cheap ASDA bottle that I also sometimes use is terrible at this, and always smells of blackcurrant squash - even though I only filled it with blackcurrant squash once about a year ago! Regarding the Thermos's bad points - there's only one problem... leakage. 99% of the time the bottle is absolutely fine - but there have been a couple of occasions when the contents have leaked inside my sports bag, which is most annoying.
- - - - - - -
The majority of the time the Thermos Hydro Sports Bottle is an excellent drinks vessel which performs well - the Ice core running through its centre works especially well and is an ingenious solution for keeping your liquids cool. The leakage problem is certainly a downer on the product as a whole - and although it's only happened around twice in fifty uses (both times the lid *was* screwed on correctly), it's still an issue which needs addressing.
Last summer, I intended to make the most of the school holidays and take my kids out as often as I could. My husband works weekends as well as weekdays so we never had the use of a car, so it is a matter of using the local amenities such as parks, paddling pools, and play areas. So this usually means a lot of walking (and thus generating a thirst), and with me being the tight fisted person that I am, I like to take food and drinks with us, to save spending money while we are out. Now I always used to go prepared for the children, but I would often forget about me, and I could be seen swigging from a child's sippy cup, just to quench my ever growing thirst without having to spend over a pound on a bottle of water.
However, on a late night trip to Tesco I spotted this Thermos bottle, and I think it was about £5 or £6, but with it being Thermos I thought it was worth the money, and would last me a long time. The fact that it contained an ice tube was an added bonus, because there is nothing worse than a luke warm drink on a hot summers day.
The bottle is a nice bright design with a good shape for an easy grip. The lid is a large screw top with a rubbery grip which makes tightening and untightening the lid much easier than it would be had the lid been completely plastic. On top of the lid is the drinking spout and this has a flip top lid, which can be a bit stiff to open and close, but this only enhances the fact that it is water tight; there is a rubber seal within the flip up part which helps keep the water inside the bottle. The flip top part flips right back so that when you are taking a sip, you do not get bashed on the nose by the lid. The actual part that you drink from is oval in shape and allows you to drink easily from the bottle and get a good mouthful.
The bottle holds 450ml of fluid without the ice tube, but when the ice tube is inserted it holds just 400ml. I find that 400ml is enough to keep my thirst at bay on a day out with the kids. The ice tube is a cylinder which also has a screw off lid, and you fill this with water, replace the lid and freeze. The part that screws off is just a bit wider than inside of the neck of the main bottle, this is so it sits nicely within the bottle and does not rattle around once the main lid has been closed.
I though the ice tube would make a lot of difference to the temperature of my drink while I was out and about with the kids, but to be honest the water was never ice cold and I don't think the ice tube really affected the temperature of the water. I think once the ice tube was within the liquid inside the bottle it was immediately starting to thaw out, and by the time I came to drink it, the water was at standard temperature anyway. So after a few uses with the ice tube, I stopped using it because I felt it didn't make a difference, and without the ice tube inside I could get more water in the bottle.
The main thing I was depending on with this bottle was whether it was leak proof because I despise drinks bottles that leak, I struggle to find something suitable for the children that is leak proof, so I was very interested to see if this bottle did the trick. And thankfully it did, so far after rather a lot of use I have had success every time, I can put this bottle in my bag safe in the knowledge that there won't be a growing wet patch by the end of the day.
I really recommend this bottle for everyday use, as well as sports use (as I think that is how it was intended). I can confirm that it doesn't leak and can withstand a lot of jostling about inside my bag, but it also fares well in the bottom of the buggy, often found laid on its side; and it still refuses to leak (whereas the children's drinks leak the minute they are moved from upright position). The bottle has been through quite lot in the few months that I have owned it, and it still works as well as it did the first time I used it.
Available on Amazon in pink, blue or charcoal for £4.99, they also do a 700ml version for £5.99.
Thermos Hydro Active Sports Bottle
I own and have owned quite a few different sports bottles, among some of the more used ones is this Thermos Hydro Active Sports bottle. At the time when I bought this I was surprised to see that Thermos made anything other than flasks and travel mugs. Being a form the Thermos brand made me think that this would be a good sports bottle as I have had a travel mug from them for years that has served me well.
Sports bottles are really a useful item for a whole host of activities and I use mine while working out, but I also used to take it to work with me to fill up with water instead of always buying bottled water. I have also found that this is great to bring along on relatively short hikes. The bottle I own only holds less than half a litre of water so it is best used in places like the gym or work where you can fill it easily.
It has a contoured body which makes it easy to hold even with slightly damp and sweaty hands from participating in sporting activities. The lid on this bottle can be a bit temperamental and you really need to check that you have it tightly in place because it can sometimes leak if you are not careful. One of the features that I really like about this bottle is that it has a wide spout that lets liquid flow freely, which compared to some of the sports caps means that you can have a larger swig at any one time.
This bottle unlike all of my other sports bottles has an ice tube that you can use to keep the water even cooler to drink. Personally, I don't use this, mostly because I don't remember to use it. Although I do think it is quite a nice feature if you would get the use from it.
I have seen this bottle available in a multitude of colours, personally I own a 0.45 litre bright pink version. It is quite a small sports bottle, but it does hold enough for a short workout or general use. I do also own a litre sized sports bottle and I tend to use them less because I find the added size and weight can sometimes be more of a hindrance.
This is supposedly dishwasher safe but I tend to just give it a good scrub in the sink with hot water, personally I would be concerned about this surviving the dishwasher.
I bought mine quite a while ago from a local sports shop, but not remembering how much it cost I did a search online and Amazon are currently selling them for £2.63. However, regardless of where you find this at most it should be around £5 to buy. I have used mine quite a lot and for the money I paid this has definitely been good value for money.
This get s a pretty good four out of five star rating from me, it is an ok sports bottle but probably isn't my favourite, but I do get a lot of use from it because of its size making it easy to carry around. Depending upon what size or what function you have in mind then this would make a good sports bottle.
I must say I love the Thermos brand and own many of their products. The most recent one being this Hydro Sports Bottle. I paid 8 euro for it in Lifestyle Sports which was a bit expensice for a water bottle but when you think of the money you would spend on buying a bottle of water everyday then it really is a bargain!
The bottle comes in many colours and hold 500ml of liquid. The lid is spill proof and can easily be flipped up with one hand. Essential when on the treadmill! It is made of plastic so its light and durable. I have had aliminium bottles in the past and they were constantly dented from being dropped so I like how this bottle can hold its own.
Its has a good grip as it is in an oval shape and wont slip out of your hand easily. My daughter who is two years old has no problems holding this bottle. Although I cant say I would recommend this to a child her age because she has difficulty in opening the lid to drink out of it.
The base of the bottle is quite wide and this is the only thing I dont like about the bottle as I cant fit it into my drinks holder in my car. However it does fit perfectly into the drink holder of my York treadmill.
The bottle itself is not insulated so if it was sitting in your car for a few hours in the summer the contents will become very warm. As I live in Irish weather this rarely causes problems for me! However if you wanted to use this bottle in hot weather then it wouldnt be very good.
Also it only takes cold liquids just in case you think you can transport your soup in this! The name Thermos usually brings the thought of soup into my head.
Highly recommended water bottle for on the go. Saves you money if you are prone to buying water bottles for lunch everyday and also helps our enviornment!
I bought one of these bottles for the car. I hate driving or travelling with its a hot day it hurts my head and i over heat. I don't drink fizzy juice and i drink shed loads of water but only if it is cold nothing worse than a warm bottle of water.
I spotted the thermos hydro spots bottle in my local B & M store for only £2.99 so i bought it. The shop only had black or red bottles left so i went with the red bottle same as the dooyoo picture.
Thermos a good brand and i remember when my dad used to take his thermos flask to work, they are hard wearing and last for years.
The sports bottle is made from aluminium metal and is very light.
Thermos sports bottle has an oval shaped hole on the top so the water can be poured into the mouth without having to suck on the round valves you get on sports bottles, it also allows the water to come out faster giving me a bigger drink from the bottle.
I really liked the idea of that i have thrown many sports bottles in the bin because my girls have chewed the top of them.
The oval shaped hole also has a cover joined onto the bottle this pushed into the hole to block it and stops any spillages or leaks.
On the lid of the bottle when unscrewing it is a long silicone tube this fills with water and the whole lid should be put in the freezer over night the tube has frozen solid and putting it back on my bottle in the morning lets it keep my water nice and cold for the next five hours, i think its a great idea and i am pleased with the results.
I have only one had a problem when the bottles leaked all over my car seat and was my own fault i hadn't pushed the cover properly on the drinking hole and the water escaped but apart from that never leaked. It is so nice to have a bottle of cold water in the car when its hot.
I highly recommend this thermos sports bottle.
As part of my continuing search for a child's water bottle that doesn't leak or break after a week, I tried the Thermos water bottle recently.
For my kids I bought both the 450ml in blue and the 700ml in grey from Wilkinsons, for £4.50 and around £6 respectively.
They have a plastic core that unscrews so you can fill it with water and freeze it, then fit it into the bottle to keep the drink cool. This worked really well and was a big hit in the hot weather, although I nearly killed the central core the first time I used it, by overfilling it and causing the plastic to split. Also, having to accomodate the frozen section means the bottles are quite big and chunky - possibly a problem for some bags.
There's a nice wide drinking spout, with a rubber-edged lid that was properly watertight at first. But after a couple of weeks both lids had splits in from general knocks and bumps at school, and my son's started leaking. As he carries his bottle round in his bag with his books I replaced it. His second bottle leaked from the start though, despite me closing the lid really carefully, and we had to abandon it.
We persevered with my daughter's bottle for another week or so until one day it got clonked at school and the frozen core sheared off from its top section that holds it in place.
I binned them all!
I really liked the design of these bottles at first, but they need to be a lot stronger to cope with the rigours of school.
When the Summertime comes and there's some nice weather I like to step up my activity and play sports like Football, Basketball and sometimes Tennis. I was looking for a Sports bottle which would be ideal for carrying around for when I needed a refreshing drink after or during a game. I found this particular 500ml one on amazon for around £4 in the Red shown. You can also find these bottles in 700ml and 1 litre sizes which will be a little more expensive. I was looking for something that was sturdy and kept the drink cool and had heard good things about this one so I opted for a bottle.
The Bottle I bought was the red one but you can also be find this in a number of other colours including Pink, Grey, Blue and also Black. These bottles have a special ice tube which slots inside the bottle and is designed to keep the drink inside a lot cooler than other Sports Bottles. When you have beeng playing a sport or walking for a while and worked up a sweat you want a cool drink to cool you down and refresh you. I have sometimes been put off some drinks bottles by the strange taste which they can give your drink. This bottle however works really well and does not give any other taste at all, Just the taste of the drink inside.
The cap is easy to use and gives you a spill resistant flow of the drink. You can use a variety of cool drinks in this bottle and the Ice Tube will work really well. The bottle is ideal for anyone whether they are using the bottle for soft drinks, energy drinks, water or even supplements if you are into weight training etc. This bottle is also ideal if you are a longer walker as it will keep the drink cool for a while before you may stop. If you are using this while riding your bike then it will hapilly sit in your bottle holder.
This is a very good sports bottle as it is versatile, keeps your drinks cool and is also a very smart looking design. These make for a very good product and one I would recommend for anyone who likes to take part in Sport regularly and if you are going camping then this is also ideal as you can use it around the campsite as well as when you go out and about around the local area. A top product which gets my five stars.
Once upon a time we had a water machine at work which dispensed lovely cool water, but since moving offices we've lost our water machine and so I now have to take my own water (the tap water there is awful!). However, filling a bottle with water tends to mean it's warm by the time I've been at work for a short while. During the summer I resorted to freezing the bottled water just to keep me cool, but then I found it wouldn't melt as quick as I wanted to drink it. Argh! I needed a solution.......
I found that solution while shopping in Tesco... The Thermos Hydro Active Sports Bottle. This isn't just any sports bottle, it's one with a "Refillable Ice Tube"! The removable ice tube sits neatly in the centre of the bottle and is simply removed, then filled with water before being placed in the freezer. Once frozen, simply fit the ice tube back into the sports bottle and then fill to the required level with water (or another type of drink) and put the lid back on. (Please note that this sports bottle is for non-carbonated drinks only). My office at work is quite warm due to the amount of computers and equipment in it, but I still found that water in the sports bottle was still fairly cool a few hours later.
The Thermos Hydro Active Sports Bottle is made from BPA free materials. This means that the product does not contain Bisphenol A (BPA), which is thought to be a health concern, so you can be sure you are drinking from a safe container with this sports bottle. Also, using this sports bottle rather than a disposable water bottle means you aren't throwing away a bottle every day (as I've noticed a lot of water bottles these days tend to say not to refill).
I hate those sports bottles with a lift up lid where you have to "suck" the water out and it dribbles out, so I was glad to see that this sports bottle simply has a flip up lid. Upon opening the lid you can see that the oval opening is just the right width to drink from. However, I would like to note that you have to ensure you have push the lid down enough to seal the bottle so that it doesn't leak. I ensure mine is closed properly and I've yet to have a problem with leaks, however I have heard of some people having problems with the bottle leaking but I would think that they've simply not pushed down on the lid.
Despite the wide-ish opening to drink from, Thermos claim the bottle is spill-resistant... I've yet to test this theory as I don't tend to go throwing the bottle around with the lid open, but due to the shape of the bottle it does look like very little would come out should you accidentally knock over the bottle. The bottle has a contoured shape and is easy to hold. I wash my bottle in the sink with the rest of the washing up, but this sports bottle is dishwasher safe should you want to throw it in the dishwasher.
As far as I'm aware, the Thermos Hydro Active Sports Bottle comes in red, blue and charcoal grey. I have the charcoal grey one and it's see-through so you can see exactly how much liquid you have in the container.
I bought my Thermos Hydro Active Sports Bottle (450ml) from Tesco for £4. Larger sizes are also available, but this one is just the right size for fitting in my work bag.
Would I recommend this? Definitely! Even somebody at work commented on how useful it seemed, what with keeping the water cool, and they were thinking about buying one for their daughter to take to school. Useful all round!
With the rather short hot spell we experienced a week or so ago, I needed to find a drink bottle that would keep my children's water cold for as long as possible in the classroom. It is one of the rules of the school and the pre-school that the children must have access to water at all times with as little disruption to the lesson as possible. Sports bottles are the ideal solution but the contents can easily become warm in the hot classrooms and then the water is even less appealing to the children than it was before.
I saw these in Robert Dyas for just £3.99, which I thought was a very good price for it, although I have also brought a similar version in Woolworths for a pound more and these have proved to be superior to the Woolworths version in my opinion.
The basics of the bottle are better than a sports bottle because they don't have the round valve that you need to suck the drink out of. These can become chewed and bitten with the children and end up in a very sorry state, while the rest of the bottle is intact. These bottles however, have a simple oval shaped hole at the top. There is a cap that fits over the hole with a rubber seal around it to make it a tight fit and prevent leaks, but the hole where you drink directly from means that it will flow freely out when the cap is removed and therefore your child can get a better, fuller drink from it than having to suck from a valved sports bottle.
My son prefers this type of bottle and at 7 he is quite capable to drink from it without tipping half of it down his school shirt, but my daughter does find it a little trickier and prefers her valve cap as it provides a slower drink and at 4 this is probably a wise move. In terms of my son, the faster flowing hole means that he will drink more each time he has some and this in turn means he is much more likely to finish his water during the day, meaning he is better hydrated in the hot weather. This is a very positive thing in my opinion, having already experienced him feeling ill due to the heat and not enough water consumption.
The other important and excellent part of this bottle is the ice pack that runs through the centre of the bottle. This is what keeps the drink cold for approximately three or so hours. My son tells me it is nice and cold until approximately lunch time, when he has drunk the majority of his water anyway. The mechanism is very simple with just a plastic tube with a twist off lid that sots inside the bottle. You fill it with water and pop in the freezer over night, then take out and place inside the bottle which is filled with water. The ice pack tube keeps the water cold much the way an ice cube would but because it is inside the plastic tube it stays frozen for longer.
I have found putting the water bottle (with water in it) in the fridge over night, then placing the ice tube in helps it stay colder for longer as the water is very cold to start with.
I think these are perfect for school or work, giving the child or adult 0.5L of cold water at a time. I have spoken to my son's class teacher and asked her to make sure his bottle his filled up in the afternoon from the water fountain so he is drinking the maximum amount possible. But £3.99 for a dishwasher safe, reusable bottle that won't wear out certain parts before others is ideal for my needs, and as they come in blue pink and clear they are ideal for girls, boys or adults.
Essential summer gear.
Freezable, dishwasher safe, water bottle for general sports use.
