Bivy + Cuben Fiber/Down Quilt

Eugene has it right.

I buy the cuben from the manufacturer (Cubic-Tech) and the momentum is from Thru-Hiker. Both are great companies to deal with.

Just ordered the materials for my bivy. I got .60oz Cuben in Lime Green from Z-Pack. Nanoseeum, #3 coil zipper, .90 Momentum in Coyote Brown from Thru-Hiker. And mylar tape (optional) from Quest. Soon it will be time to sew this thing up and have a nervous break down doing it.

Thank you all for the help.

Note: If any body has a good hood design, can be attached to tarp without a lot of folds in it, let me know. I'm going for a single seem border (not bath tub) like Steve's bivy.
