I don't know why people are complaining about this bag, maybe they are doing something wrong. I have had no problem with this bag at all. Took this on a cross country trip with lots of hiking and the only problem I had was that I ran out of water every now and then. I have had 0 quality issues and love the quick disconnect of the hydration bladder. If you find it difficult to remove just use the quick disconnect and leave the hose where it is. This is supposed to be simple. I took this from the hot and humid south to the dry and arid desert and had no problems with comfort and usability. My back did get a little hot and sweaty during some hikes. I loved how adjustable the bag was in finding that perfect fit. you gotta change your bag for different scenarios, not all the woods and hikes are the same. This bag will continue to serve me well. Great purchase.
