Within the micro-environment there are two factors that determine comfort:
1. Humidity in the space between the suit and the skin
2. The skin temperature
The body's primary cooling mechanism uses the evaporation of sweat to dissipate body heat.
A material capable of supporting this natural cooling cycle allows moisture to pass freely through to the exterior.
As moisture leaves, a lower humidity level is recorded in the micro-environment.
In controlled comfort studies utilizing simulated working conditions (moderate work rate at 300 Kcalories per hour for up to 90 minutes-equivalent to drilling or abatement work tasks) in warm and hot environments.
Kleenguard SELECT and Kleenguard Extra were shown to have low micro-humidity over the duration of the work period.
Lower micro-humidity means that more sweat is evaporated through the material and the worker remains cooler, longer.
A more comfortable worker can be more productive.
