Here goes an epic idea...
what if I were to make a hammock out of Epic fabric? its denier is 30x50, so it is a little weaker then 1.9 oz length wise, and 1.1 oz width wise. I got this idea from the PBP podcast, the interview with MLD. That is what they use for their hammock, but I cannot find it in their site (the shop is malfunctioning).
since Epic is usually polyester, it will not stretch as much, and each thread is bathed in silicone. The threads will be stronger then the uncoated/ DWR in the 1.9 oz RSN that we use. It should hold fairly well, and it is 1.7 oz.
I am going to try and get samples from as many places as possible, and see if I can find one that is more breathable/ waterproof then the rest.
if it does prove good, I would try and order wholesale, because it is quite cheaper per linear yard (~$3 at OWF). I would only need about 3 yards, so there would be anyone else would would want a 1 layer WP/B?
the bad news is that is around $10 /yd, but I am going to see if I can barter it down a bit.
