Thread: Sleeping mat, insulated or not?

I always thought the trapped air inside the mat/lilo worked as insulation....I took the piss out of my 3 companions on duckshooting opening weekend they all had stretchers UNTILL my cheapho air matress burst...luckily my daughter took pity on me and gave me the closed cell foam mat for Saturday night. I usually end up sleeping on clothing,not to add warmth but to add padding so my arms dont go numb during the night.
