Value Assessment

Excellent entry point for cooling. While it won't 'chill' like a powered unit, it is the most effective passive solution for the price.

Why Not Alternatives?

Superior to standard 'cooling gel' pads which eventually saturate with heat; the PCM technology actively cycles heat away from the body for a longer duration.
