I made a DIY HH style hammock for a friend from 1.9oz Ripstop from Hancocks Fabric. On a recent trip, it died, on it's first use. The fabric tear started about where his heels were and progressed rapidly all the way to the butt area until it the hammock was no longer occupied (it dumped him). The failure was not in or near any seam or stitching and had nothing to do with the design. I think I got a hold of some faulty fabric. He probably weighs 205# and it was real DWR ripstop.
Just an FYI to the group.
