I just hung out in a Tyvek hammock. I'm taking bets on how long it will last.
Factoids: size, 10X6; construction, whipped ends on 1.5" webbing, Tyvek taped edges; structure, static line; my weight, 230#.
The idea was to come up with a simple way to have a windproof, waterproof but breathable hammock without having to hang layers of other stuff under the hammock. Tyvek would fill that bill -- if it doesn't ...er, let me down.
