I have made a light, UQ ,about 13 oz I believe ,out of a nanatuk down bag. Removed the foot box and put stretchy stuff all around. then I sewed the .33 cuben on the bottom of the Nanatuk. that adds only .7 oz, and makes a good weather/splash/spindrift shield. works like the one Grizz is talking about, except my cuben is not on the hammock side.(for the weather protection.) no reason why the double cuben quilt would not work as long as you have some way to let it breathe.gnome
I plan on making cuben uq and tq to shave off alot of weight. I do not think it would work good in a hammock because if you get in with sand on your but, rub around enough, you will rub a hole in the cuben, at least thats what i think since working with some. I dont think tears would be your enemy, instead, i think daily abrasion from velcro, buckles, zippers, and grit would do a cuben hammock in.
