But back to serious- for the moment anyway- I don't think we winter hammock hangers are in much danger of failing to lose enough heat to survive while winter hammocking. But, even though we most likely are still losing some heat through various processes, we do ( or pretty close) totally eliminate that one form of heat loss (evaporative cooling) when using a VB. It's hard to evaporate in a sauna suit!
Do you guys think the benefits of a space blanket are significantly due to blocking radiant heat loss as well as normal VB effects? Or, is it in really mostly due to VB effects?
