It is a dry bag. There really isn't much you can say about them. I used it for adventure racing and it kept my gear dry. I love the air release valve - I wouldn't buy a bag without one. I bought the 5 liter and it fit my extra set of clothes, some TP, and a few Cliff bars and fit inside my pack without a problem.
