I still don't have a hammock yet, but am already beginning to plan for quilts, both over and under.
I have two Sierra Designs down bags that have their "Drizone" waterproof/breathable shell. These are wonderful bags and the waterproof shell is the real deal. Their shell material got me to thinking...
Would an outer shell similar to Drizone (or any other waterproof/breathable) fabric laminate work for an underquilt? Would this cause trouble with condensation? I do not experience condensation problems inside the sleeping bags when in use.
My thought is that this shell would protect the underquilt from getting wet from splash or wind-driven rain. I understand there might be a miniscule weight disadvantage, but seems worth it compared to carrying another "under cover" of some kind.
