We recently had a customer that tested the cooling effect of our HyperKewl fabric when placed inside a hat using an insert. The results, as demonstrated below, were quite remarkable. There was over a 35 degree difference between the temperature at the brim and the temperature inside the hat when the insert was saturated (soaked in water). Now keep in mind that this was a basic test not conducted in a research facility, but would be more akin to field testing under various controls. Nonetheless, the results, or rather impact on cooling the individual, were impressive enough that we thought that we would share some of the data.
