Okay so I understand that a sleeping bag doesn't maintain it's heat underneath due to the compression taken on by your body weight, (tried and tested hehe), but I see a lot of heat is lost by the air flow underneath the hammock. My question is. . . would a waterproof or water resistant bag, such as an REI Expedition bag, help any?? I figured if it's waterproof, it's gotta be windproof as well. I've got a -20 degree bag, and hoping to use it in 10+ weather.
Any input would be great. I haven't seen a thread on the forum asserting this question or asking for experiences yet.
