by fromWaterproof, but not durable... Way too thin to be a reliable dry bag. I bought this bag brand new for a 5 day canoe trip through the Green River in Utah and on the 4th day this bag ripped through the side. It just isn't durable enough to use on a multi-day expedition. My old Sea Line PVC bag held up just fine.

by fromKeeps it dry I took this on my trip to Quetico Park in the Boundary waters canoe area to keep all of my clothes dry. There were some rain storms that went through and this dry sack kept everything bone dry. Good quality product. Only downside is it does not compress.

by fromAbsolutely perfect This product is an ultralight solution for backpackers. It's not for beer-swilling canoe trips down the river. There are more heavy & heavy-duty products for that sort of recreation. I backpacked the slot canyons of Utah, east of Zion NP for 3 days with this dry sack. It was great. It kept my prized, down sleeping bag (and clothes) dry the entire time, even during submersions. When the sleeping bag was packed inside it, I sat on the sack to compress it and then sealed the clips. This actually makes it a compression sac. My backpack has never had som much room. Take good care of it and it will take good care of you.
