Jeremy C.wrote a review of Exped Schnozzel PumpBag on July 19, 2012
I love multiple use gear where you don't end up sacrificing anything. This thing works so well as a pump, just fill it up and compress, only takes a few pumps. Plus it doubles as a super-lightweight, big dry bag. Personally I don't like taking multiple dry sacks, nor do I like taking massive pack liners. For me the 45L capacity (which is not stated on this page) is a perfect size to put sleeping bag, clothes and food in. And best of all you get it at no weight penalty: this weighs 70g while Sea to Summit's biggest dry bag weighs 65g and is only 35L!
Bottom line: if you own an Exped mat, get one! And ditch your old dry bags while you're at it.
