Do Guardian Caps Keep Helmets Cooler?

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

BioCore tested the Guardian Cap NXT, the model mandated by the NFL, and data proves that helmet temperatures were 9-18°F lower with the Guardian Cap compared to the bare helmet.

The Guardian Cap can help reduce the temperature inside the helmet by reflecting direct radiant heat from the sun or through its material properties.

Let’s Put it to the Test

Our team put this to the test in our backyard and we noticed a 12 degree difference from a helmet with a Guardian Cap compared to a helmet without a Guardian Cap.
