Do Guardian Caps Reduce Radiant Heat?

A concern we often hear is that Guardian Caps might make your football helmets hotter. This is not true. Independent research shows the opposite.

The NFL has done a heat study on the interior temperature of the helmets and their data proves that the Guardian Cap keeps the internal temperature at least 20° cooler. The reason: while polycarbonate conducts heat, the foam of the Guardian Cap does not, and acts more as an insulator.
