I used this Hex 2.2 XL nylon PU to make an extra wide, heavy duty winter tarp for my backyard hammock site. I live on a stormy ridge in NC with frequent 40mph and occasional 60mph winds. My 1.1 silpoly tarp has been torn several times by wind and my UL 0.9 silpoly was recently eviscerated beyond repair. The Hex 2.2 tarp is a little bulkier, 3 times heavier but much much tougher. The Hex 2.2 sews great compared to the lighter silpoly. For long distance backpacking, my 1.1 silpoly is a lighter option, although the Hex 2.2 is an option. But for my long term, exposed backyard site, I love the reliability of the Hex 2.2. Thank you RSBTR for great service, technical specs and a wide variety of quality products.
