The Cooling Capacity of HyperKewl PLUS

We recently completed testing with SGS on the cooling capacity of our HyperKewl fabric. The results were better than expected. HyperKewl PLUS fabric, when quilted as the middle layer between a waterproof nylon and a breathable outer nylon, generates an average 0.231 W/cm2. In terms of the cooling capacity of a standard vest (6529), that equates to up to 2287 BTU/hr of cooling from HyperKewl PLUS. Considering that a small air conditioner generates up to 6000 BTU/hr, the capacity of HyperKewl PLUS to cool you down is very impressive.
