With this kind of weight it is definitly something I am going to look into in the future. I think there are plenty of other things in my setup right now I can change to lighten the load. After I get everything else where I like it, I'll have to look into this stuff.
A couple of questions. Do you think this stuff would hold my 220+ lbs self? Also you are talking about use as a tarp and rain gear. How do you think it will repel water after some use? I am wondering if it will hold up to a lot of use.
Also in terms of getting a better feel, have you considered washing it first? People have used the on tyveck and had good sucess with it loosening up the fabric.
