Cooling times vary with the application and the environment. In environments where the qualities of active evaporation can be realized, Hydroweave® can cool for hours. The chart characterizes testing by Auburn University of Hydroweave®'s evaporative cooling times to that of a conventional fabric at varying temperatures from 70°F to 170°F (21~76º C). In this test, Hydroweave® was shown to cool an outstanding 125 minutes (2 hours and 5 minutes) at 170°F.
 
Hydroweave® was also proven effective as a passive heat sink for fully enclosed applications. In tests, vests made from Hydroweave® were worn beneath poly-coated encapsulation suits and proven as an effective deterrent to heat stress, increasing work time by an average of 16.4%.
 

 
Expected performance of BodyTeq Apparel

The cooling performance of BodyTeq Apparel will depend on the following:

1. The length of time the Hydroweave® core absorbed moisture.
Refer to Activation Procedure for specific products. Hydroweave will absorb water for up to five minutes, but additional time may be recommended if wicking is required to evenly distribute moisture.
 
2. Humidity.
Higher humidity will slow evaporation, producing less cooling, but over a longer duty cycle.
 
3. Temperature.
Higher air temperature will increase evaporation. On still days, the initial sense of cooling may lessen as the body adjusts to the cooling affect. However, the garment continues to remove heat, and its contribution is dramatically felt if the wearer moves into an air conditioned environment.
 
4. Wind speed over the garment. Higher wind speed increases evaporation and cooling. On motorcycles, vehicles, or bicycles, leather jackets or windbreakers may be worn over the garments and opened to regulate cooling.

Based on these parameters, expect cooling from 1.5 hours on a motorcycle or vehicle on a hot dry day, to as much as 5 hours walking on a more humind day with less wind over the garment.
