I found this interesting insulation product in a Daiso Store. If your not familiar with Daiso, it is a Japanese dollar-style store, where most products are $1.50 each.
This roll of insulation is foil on one side and white poly foam on the other, 70x200cm (27.6"x78.7") and 1.65mm(0.065") thick. The whole roll weighs 104g/3.6oz. $1.50 per roll!
I think it has great potential for building cozies and protective insulation for fragile air mattresses. I'm very interested to see how it works for supplemental hammock insulation.
