This is straight off of the website above;
"Other insulation materials require loft to achieve their insulation value. Pressure causes these materials to compress dramatically and lose their loft along with their insulating capacity. Aerogel does not need loft to deliver its high insulation value and it barely compresses, even in a foot bed under adult weight. At 15 psi pressure, it retains over 85% of its original thickness and over 97% of its original thermal performance. No other insulation can match this performance. Aerogel is a high performance insulation used in place of lofted insulation."
I take that to mean that it's not compressible in the least. I think there could be a real advantage to wearing it and sleeping in it provided it isn't super heavy.
