"Protection versus flexibility. Style versus comfort. The Dry Case Waterproof Backpack is almost the great bridge between these bifurcate needs. The Dry Case Waterproof Backpack has a smart little air valve at the bottom that lets you squeegee out any captured air, once you have the pack all sealed up. In this way, you can really get the pack down to a slim profile almost like a vacuum seal. An interesting concept. Despite its definite outdoorsy stylings, I actually like how the bag looks. It's fairly sporty and, as noted, can have a slim profile. The two-tone black and blue is pleasant enough. The shoulder straps are hearty and comfortable. There is also a belt strap which would be a bonus for walking distances. Does the the bag smell like a new radial tire? Yes, a little. Will it keep the stuff inside dry? Totally. Is the bag great for camping? Absolutely. Can you use it for daily office life too? Yes, with a few concessions. I myself would use this for a daily pack because the waterproofing capability outweighs the other issues for me and I like how it looks. At $89.99, it's on par with, or cheaper actually, than a lot of different bags out there." - TechCrunch Review

      This is the perfect waterproof backpack for any active person who wants to bring their belongings along with them during any adventure. The backpack is 100% waterproof and is one of a kind, because of its handy purge valve. With the purge valve you can inflate or compress the backpack, and even use it as a draining tool if using the backpack as a shower or cooler. The backpack includes a fully waterproof main compartment capable of holding 30 Liters, an internal zippered waterproof pocket to store smaller items, a front mesh pocket so you can keep wet items out of the waterproof area, side water bottle holder, bungee cords that can hold your other DryCASE items, and lots of padding on the shoulder straps and back support for a comfortable hold.
