Review on Waterproof XPEL Dry Bag by Wilderness Systems - Convertible Shoulder Strap & Valve for Cooler Functionality by Richard Jarvis

This isn't the smallest stuff sack you can find. exists without additional No valve, no D-rings, simpler connector design. It's also a little thicker. But. For getting the job done and ease of use, it's hard to beat. The one-way valve is a potential point of failure, but it's certainly handy to have. The valve makes a big difference in closing/folding speed and efficiency. Remember that you cannot overfill these bags or they will lose their water resistance. You need a minimum number of reels to keep them waterproof. I was a little worried about this bag tearing because it's made from medium to light weight materials, but so far it's survived about 2 dozen canoe and kayak trips with no issues.
