Phase Change Cooling

Introducing CoolPax™

CoolPax™ is our unique Phase Change Cooling (PCM) technology.

Our PCM cooling products use CoolPax™ technology to keep you cool.

How Does Phase Change Cooling Work?

CoolPax™ contains a lighter-than-water, non-toxic carbon-based liquid, that absorbs heat as it changes from a solid to a liquid.

CoolPax™ freezes at 58°F/14°C and remains at that temperature for 2-3 hours.

Activate CoolPax™

It’s easy to activate. Just place the CoolPax™ in the freeer or in ice water for 30-40 minutes.

Insert the activated CoolPax™ into your garment and enjoy 2-3 hours of constant cooling power.
