Great bag.... mouth piece though....
The Hydromedary bag is the best on the market! Tough, light, durable, and holds the water well to fit in you pack sleeve. My problem came witht the mouth piece. It has a two-piece system and can slide easily out of the water tube. This happened on an outtin. My leg became wet because water was leaking out of it. I put it back in place, and have not had an issue again, but it is always on my mind now. I won't leave the bag in the tent over night because of it.
