Improved fabric is softer, quieter, textured, no-slip, and features enhanced next-to-skin-comfort. Unmatchable warmth-to-weight ratio. Multiple layers of reflective Thermacapture technology traps radiant heat, and Triangular Core Matrix construction minimizes heat loss without the bulk and weight of insulation. 2.5 in. baffled construction for stability, support, and comfort.
