What Is CoolPax?

CoolPax is made of Phase Change Material (PCM) cooling technology. It uses a non-toxic carbon-based liquid that freezes at 58F/14°C and remains at that temperature for 2-3 hours. Simply place CoolPax inserts in freezer or ice water for 35/40 minutes and insert into garment pockets.

Science Behind CoolPax-

A Phase Change Material (PCM) is a substance with a high heat of fusion which, melts and solidifies at a certain temperature, and is capable of storing and releasing large amounts of energy. Heat is absorbed or released when the material changes from solid to liquid and vice versa; thus, PCMs are classified as Latent Heat Storage (LHS) units.
