I have raingear made out of it, amazing stuff. FroggToggs. They used to be relatively cheap, and EXTREMRLY lightweight. However, their popularity caused a price increase...the wind/waterproofness of these are great though. I spent about 2 hours hiking in it, kept me dry (except for sweat, they DONT vent)and are virtually windproof. I think they would make a great shelter cloth. I have heard people say this stuff tears easily; I havent had mine tear yet, but, thats what duct tape is for!
