I have bought the bag for universal use. On the one hand I am much in the natural way, but also in the city, for both it is suitable. It has for example a lot of space. a Nalgene bottle Everyday wide mouth goes in perfectly. Small pocket on the support for phone or camera, a compartment for glasses, everything has its place. The material is very robust due to the Molle system can expand the bag, I have two Tasmanian Tiger Tac Pouch 1, 15 x 10 x 4 attached. Bursting never fully satisfied, I would buy the bag again.
