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

A phase-change material (PCM) is a substance with a high heat of fusion which, melting and solidifying at a certain temperature, 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. TechNiche uses phase change material for cooling.
