Yesterday, I picked up a couple hundred yards of some very nice 30d Coyote ripstop nylon.
Weighs in at 1.0oz (actually .985oz)
Pure finish, no coatings or dwr treatments at all, very breathable.
It's 67" wide.
Now available for the Darien UL and all other Dream Hammock models.
This and all the other fabrics can be seen at http://www.dream-hammock.com/Fabric.html
