I have one of these "Sportsman's Blankets" and it's quite nice. I keep it in the truck for sitting on or emergencies. I just bought a my first hammock (a blackbird 1.0 DL) and am looking at keeping under insulation on the cheap. The way I see it, for Spring through Fall it appears most people use very thin foam which insulates a bit but mostly blocks wind and creates a barrier. Would a reflective blanket do the same thing or am I underestimating the insulation powers of 1/4" foam?
I also have a few nice full length sleeping pads (Stoic, Thermarest, and a Nemo), would these be any better than a reflective blanket?
On an even lighter note, anybody try one of these?
