How it works...The products manufactured by CoolMedics are constructed from a patented three-layer fabric that by combining hydrophilic fibers into a fibrous batting core and a thermally conductive lining, will provide cooling after allowing the product to soak in water for 30 seconds to one minute. Not longer.

The water activates the cooling process by charging the fibers with moisture and creating an environment for evaporation. When moisture in the batting evaporates, heat is removed and cools the surrounding area, transferring the cooling effect to the wearer.
