solid bag, does what it needs to. the little slit to put the velcro through to hold the bladder up seems to be ripping a little and I've bean very gentle with it. only bean a week or so actually using it so we'll see how that holds up. for the price it's otherwise a really solid bag, good amount of room for the essentials, mouthpiece was a bit weird to sort out but once you get it going once or twice it gets easier. wish there was somewhere to hook the mouthpiece onto that holds it down a little better when bumpy, don't super like having it whack me in the face, but is mostly manageable.
