The Catalyst CryoHelmet
1. The coldness peaks at about 10-15 minutes unfortunately and is cost prohibitive.
Elasto-Gel Cranial Cap
1. Used at a sports tournament in St. Louis to cool me down. Did a great job however didn’t last for long as the cooling gel packs inside move around and settle at the lower back/lower sides due to their weight. Sadly only got two uses out of it before having to throw it out
