15/12/2007· In order to assess the non-evaporative components of the reduced thermal insulation of wet clothing, experiments were performed with a manikin and with human subjects in which two layers of underwear separated by an impermeable barrier were worn under an impermeable overgarment at 20°C, 80% RH and 0.5 ms−1 air velocity. By comparing manikin measurements with dry and wetted …
