When I noticed that the .5 cuben and .5 noseeum where basically the same weight I began to ponder an idea for a hammock bug net. Most hammock nets are designed in a sort of half circle or taco shape. Like a capital D rotated 90 degrees. With the straight side being your ridgeline and the curved part of the D being the part below you nearest the ground. I think most of you will know what I mean without needing pictures. If the upper third of the net remained noseeum mesh while the remaining lower two thirds were to be replaced with cuben fiber you should able to partially protect your insulation from cross winds and blown rain while still having plenty of ventilation and bug protection all around. Like most bug nets designed this way the bottom fabric hangs quite a bit lower than your hammock and your back will never be directly against the non breathable cuben, so there should be plenty of space for ventilation since this is only designed to be a buffer against wind and rain that comes in under your tarp (rain bouncing off of rocks and ricochet onto your back and or gear) and not intended to keep you as protected (and clammed up) as a bivy. If it would not prove to be a strain on the noseeum material then maybe the cuben bottom could act as a waterproof gear loft for an UL pack and maybe your boots. I believe there would be little to no weight penalty by combining two similarly weighing fabrics over basically the same amount of surface area as conventional designs. Sometimes I pitch my hammock tarp on the ground and jerry rig my hammock net as a mesh inner. Well there ya go, voila built in cuben ground sheet.
