  Base fabric Insulation pads
Material composition 94% Polyester, 6% elastane 94% Polyester, 6% elastane
RCT (Km2/W) 0.0086 ± 0.0007 0.0454 ± 0.0038
Air permeability (mm/s) 1287.6 ± 257.6 42.8 ± 5.4
Density (g/m2) 80 380
Thickness (mm) 0.47 ± 0.01 2.14 ± 0.02
  1. Material composition and density are according to manufacturer. RCT: Resistance to conductive heat transfer was tested according to ASTM D1518–14; a higher value reflects higher thermal insulation. Air permeability was assessed according to ISO 9237:1995. Thickness was measured according to ASTM D1777–96 (2015) under a compression of 735 Pa
