Well I've taken it on a couple trips and its a decent bag and it really isn't bulky at all. The listed dimensions are 12x12x25 but the thickness is actually only about 8" or so, pretty much like a regular backpack. The dry bag storage should not be labeled as such, its just a zipper so there's no way it could stay dry. The cooler won't keep things cold for long and it is listed as sealed as well but again, its just a zipper. For $40 delivered it wasn't a terribly bad investment as I can use it elsewhere but its not what I'm looking for. If I didn't wade above my waist it would work lots better. I'll keep looking.
