So, I love thinking about hypothetical gear that could be made, and I wonder if anyone has ever sewn with emergency blankets/heat reflective material? I'm thinking something for winter hanging, maybe sewing this material into tarp construction as a way to keep rising heat in the immediate area? I know some people incorporate it into the bottom layer - I've seen pads for instance, that have reflectix (or whatever it's called) on one side - but what about the top layer to trap heat? Same sort of idea as a hot tent in a way, creating a small area to trap and contain body heat. Especially because the tarp would probably be pitched down closer to the hammock in colder weather.
Of course there would be a weight penalty, but I figure it would be minimal, and the material itself isn't so delicate as to make this unfathomable...
Just some fun food for thought on a rainy city day
NB: maybe this idea is crazy for a reason I haven't thought of yet - I've admittedly had a few nips of scotch that I got today as a b-day present from a coworker!
