DISCUSSION<br />

Thermal responses to the different conditions were quite distinct. At both<br />

temperatures additional wetting of underwear reduces skin temperature and more so<br />

with permeable outer layer. In spite of minimal mass loss at 10 °C subjects in wet<br />

impermeable clothes cooled similarly to wet permeable. The data provide a good basis<br />

for more detailed analysis with the THERMPROTECT manikin measurements, and for<br />

validation of available prediction models.<br />
