About this Program
Since 1997, Glacier Tek has been making high-tech garments that help defend the wearer from heat stress in extreme environments. Glacier Tek products are 100 percent made in the USA, using only American raw materials — right down to the thread.
Their first product, the Original Cool Vest, was among the earliest completely self-contained body cooling vests available on the market. It it is now sold in over a dozen countries under numerous brand names.
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, 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 phase change material, a safe and effective biobased material. Glacier Tek Cool Vests are the only cooling vests on the market that feature the USDA Certified BioPreferred® label.
