Big thanks to my mom for sewing this for me...
Bottom and Hood material is Cuben Fiber, Torso material is Momentum 90. The hood is only 12 inches to allow my breath to exit easily through the opening but still protect my head from any rain splash while under my poncho. No zipper, no head net...86" Long, 34" opening, tapered to 22" at the foot. Slightly smaller then the standard but still fits my WM Versalite. I was going to make a stuff sack, but it fits easily into a sandwich bag which is waterproof, cheap, and weighs only 3 grams.
Best part...Bivy = 77 grams (2.72 oz.)
Bivy w/ stuffsack = 80 grams (2.82 oz.)
