I just bought this pack and have used it twice and I'm really liking it. The main zipper is a little tough to slide but that's what helps make this waterproof. Because it's a waterproof pack it lacks the pockets but I'm ok with this. I actually like it better. Less messing around opening different compartments as mostly everything is in one big pocket. The main reason I went with this bag was because I like to make use of the chest pockets on my jacket and my old front vest sling restricted that. This bag doesn't at all. Also way less stress on my shoulders and neck as this sits perfectly on my waist. It's got a big price tag to it but for sure a great pack that's comfortable and has lots of space. One negative is no drink holder but I have enough room inside for one, so it's not that bad.
