About Glacier Tek

Since 1997, Glacier Tek has been making high-tech garments that help defend the wearer from heat stress in extreme environments. Our first product, the Original Cool Vest, was among the earliest completely self-contained body cooling vests available on the market. Our satisfied repeat customers include Dow Chemical, General Electric, General Mills, Kaiser Permanente and the FBI. 

Glacier Tek cooling vests feature PureTemp phase change material, a biobased technology designed to absorb heat generated by the wearer. Glacier Tek vests maintain a comfortable 59 degrees for up to 2.5 hours, even in the most extreme heat, and never over-cool. Our vests offer better safety and cooling duration than that of evaporative, ice or gel-cooled vests.

Each Glacier Tek vest includes a set of cooling packs powered by PureTemp, a safe and effective biobased material. All Glacier Tek cooling packs have earned the USDA Certified BioPreferred® label, verification that the amount of renewable biobased material in the product meets or exceeds levels set by the U.S. Department of Agriculture.
