I have been using the rucksack for my photography equipment over the past year and found it to be excellent quality.
The CompuTrekker comprises a large rucksack with 3 compartments. The first is a front pocket. This provides enough space for paperwork, a large laptop charger, lots of cables and phone chargers, compressed air, camera chargers and lots more bits and bobs. I've managed to fit in all of that plus a hoodie or jumper as well. This compartment features a few pockets large enough for some A5 notepads and perhaps a small portable hard-disk too.
The main compartment provides a large, padded space for your main camera gear. The bag comes with additional padding so you can customize the layout to suit your kit. I generally fit 2 camera bodies, 4 lenses (none telephoto), 2 speedlights, snoot, grids, memory card holder and a few other accessories. This still gives me some spare room to pack in bin liners (for lying on the floor) or other bits and bobs. Very roomy.
The main compartment also features 1 large and 2 small protected pockets on front side of the bag. I usually keep thin items such as gels, AA batteries and camera batteries in these and they are semi transparent allowing you to view the contents without opening. I've never had any faults with the protection of the bag, even when packed full and it has been on planes and carried on many a photo shoot.
The final compartment is the heavily padded laptop area. I've used this for a 15.4" laptop which barely fits in but is visible on the outside. A smaller laptop would fit in completely and not be seen. This compartment has both a zip and clip lock so you can secure the laptop well.
Additional features of this bag include a tripod mounting system on the front which uses clips and bungee cords to hold the tripod onto the back, useful since it doesn't add much weight until you add a tripod but is a bit unwieldy once you've got everything packed in, then again you have half of your photo kit dangling off your shoulders so you can't expect much else!
When not in use the bungee cords do dangle around and it does take a few moments to secure them every now and again.
Another great addition is the protective rain cover which comes out from the bottom of the bag and shields everything apart from the shoulder straps from the forces of nature! It's definitely saved me a few times over. The one issue with this is that once replaced into the bottom compartment the bag doesn't sit upright and will rock forwards or backwards which can be frustrating if you take the bag to some muddy fields.
The bag is also very comfortable to carry and the extra padding on the rear definitely helps. I found that the chest strap does start to come apart due to heavy use but this just needs a bit of stitching when this happens and isn't a crucial support part of the bag - it won't fall off your shoulders because of this. Other straps have been fine with no wear or tear.
Overall a great bag with the ability to pack in an enormous amount of gear including your camera, accessories, laptop, assorted chargers and a full tripod - quite a lot!
While the price (approx £100 when I bought it) may seem steep to some it's completely worth it and this is a bag I can imagine lasting for many many more years.
