This is a great bag for those looking to carry a lot of gear. I was able to carry everything in it with out trying to play tetris. I had a great suspension system which really takes all the weight off your back, its got 2 water bottle holders on either side so if one was so inclined they could put 4 1L bottles in them, it has waist pockets for easy access. it has a hip belt and a chest belt. It is a very good bag and I was defiantly satisfied with it.
