The Truth about: Why ultralight sleeping pads lose R-value in extreme cold conditions

Executive Summary: Why Ultralight Sleeping Pads Lose R-Value in Extreme Cold Ultralight sleeping pads are engineered for weight savings, but their insulation performance degrades significantly in extreme cold environments. This article explains the physics behind R-value loss — covering air contraction via Charles’s Law, moisture-induced ice bridging, convective heat transfer, and reflective layer failure — … Read more
