Review on Skog Å Kust BackSåk Waterproof Floating Backpack with External Zippered Pocket, Available in 25L & 35L Sizes by Kyle Miller

Excellent backpack. I bike around Seattle and so far this pack has kept everything inside dry (the reflector is also very bright). My last pack, which was also waterproof, had so much fabric on the outside that it dries slowly when wet which leads to bad odors - the BackSak doesn't have that problem so I'd recommend it for a different bike. passengers. It has good padding on the back and wide shoulder straps that are comfortable for long periods of time. It's huge too - loads of room for everything inside. The chest buckle is too high and not very useful for a lot of things but other than that I would say this is the perfect backpack.
