I own two Platypus water bags one has a 1 litre capacity and the other holds 1.5 litres and they are excellent for carrying liquids while hiking or with the additional of a holding pack when bike riding however I primaily use them when hiking as they can sit within my day sack or rucksack and provide me with a constant supply of water, or at least until they run out. They are basically a flexible plastic bag (bladder) container and on one end there is a hose, you either store the full up pouch into your rucksack, I place mine between the inside of my bag and the inner dry bag that way if it leaks only the rucksack gets wet rather than the contents of the bag, ...  Read the complete review

I enjoy walking and cycling, but the same as most people, I never enjoyed having to stop every so often to take off my rucksack, dig out my water bottle, drink, put my bottle back, and put my rucksack back on. It doesn't sound like too much of a challenge I know, not like crossing a ravine on a tightrope blindfolded (not that I've ever done that!), but after the tenth stop it does begin to feel a bit inconvenient. Because of this inconvenience I tended to delay drinking until I felt really thirsty, which as we all know, is really too late to stay adequately hydrated. I bought my first Platypus Hoser about 8 years ago, it was the 1litre version, and about 6 ...  Read the complete review

I bought my Platypus hoser (affectionately known as 'Platy' in my house) when I got into walking when I lived near the Peak District about eight years ago. A Platypus is essentially a tough plastic bag which you can fill with water through a screw top and then drink through a long tube. You put the bag ('reservoir') in your rucksack and then clip the hose onto the strap of your bag so it's near your mouth and easily accessible. At the end of the hose is a 'bite valve' which stops the water coming out when you don't want it to, but means you can easily get a drink if you just put it in your mouth and bite on it. I think that this is a brilliant invention for ...  Read the complete review

The Platypus Hoser is a plastic water bladder with a short plastic hose attachment capped with a flexible silicone bite cap. It comes in 3 sizes, 1L, 2L and 3L and is designed to fit easily into a rucksack. In fact, many modern rucksacks come with a specially designed section for water bladders or at least a hook in the main section to attach the bladder to. The Platypus Hoser is designed to allow for easy access to water while hiking, biking or climbing without the need to stop and extract a water bottle from your rucksack. It is easy to use, simply remove the hose, fill with water or other liquid, reattach the hose and then place top down into the rucksack ...  Read the complete review

I have used many different bladders bought at lots of different prices. If you are serious about walking long distances then picking the right bladder is one of the the most important things. Things to think about are ease of filling, Ease of cleaning and durability. The only area this particular bladder falls down on is the ease of filling. Ideally wide topped bladders are easier as, obviously, they have a wide top to be able to pour fluid in instead of a small neck to try and fill. This one is a small screw on the bottom of which is fiddly to fill from the tap or a jug and also I worry that it will leak. I must say though that none of my Bladders have ...  Read the complete review
