The clew design is the conception of Leiavoia, who provided a detailed description (along with some of the physics) on his blog and on hammockforums. For more information about a clew suspension, see Derek Hansen's youtube video and his blog post ( all links are below).
The suspension is beautifully complicated, but not difficult to execute. Note that because I used a box-style underquilt, the suspension is not compressing the 6 oz climashield apex insulation.
The final weight is 2 1/8 ounces.
Testing of the suspension is proceeding, so stay tuned for updates.
Troubleshooting Update: after a two nights of sleeping with the quilt, I have removed the "extender" from the foot end that you see in the video. Without the extender, the quilt + suspension is 87.5% the total length of my hammock, and that is giving me a snug fit. At a longer length, I was getting gaping at the foot end and along the sides (cold butt syndrome), but at 87.5%, it seems really nice and cozy. However, I had to thread my hammock suspension through the quilt, so I can see myself shortening the nettles so that they are 85% of the length of my hammock and adding a durable extender to each side.
Materials: Approximately 65 feet of 1/16" shock cord 2 aluminum descending rings Method to attach suspension to your underquilt (I used snaps). Jig for weaving a clew (I used a few campaign yard signs, a piece of brown paper, a funny-looking pin and 8 large headed short nails). Pencil (or two). Optional: 4 short pieces of shock cord and 4 mini cord-locks (for preventing the clew nettles from tangling in the stuff sack).
