TURNOUT GEAR BREATHABILITY CALCULATOR

It’s extremely important to consider your gear’s Ret value, because your body’s ability to lose heat through conduction is eliminated in warmer or sunny conditions and it solely relies on evaporative cooling. Since THL includes a conduction element in its equation, it does not provide adequate information on how gear will perform in warmer environments which are common to firefighters.

Choose up to three combinations of Outer Shell, Moisture Barrier, and Thermal Barrier to compare their breathability.
