Glacier Tek - a Florida manufacturing company -- focuses on managing body temperature in extreme temperatures using high tech garments that help defend the wearer from heat stress. \r\n\r\nThe Original CoolVest was among the earliest completely self-contained body cooling devices available on the market, and is now sold in over dozen countries. \r\n\r\nGlacier Tek manufactures a selection of vests that feature Phase Change Material Technology - a semi-solid thermal energy storage material that is designed to absorb heat generated by the wearer. It maintains a comfortable 59 degrees - even in the most extreme heated environments - and never overcools. The Coolvest has a practical design and weighs less than 5 pounds, and offers the same cooling duration as that of ice and gel-cooled vests. \r\n\r\nThe Next Generation features RPCM Technology. Glacier Tek has recently unveiled the unique and patent pending RPCM CoolVest -- a body cooling garment that uses a renewable, agriculturally-based phase change material (RPCM) that outperforms traditional hydrocarbon-based PCM's. The exclusive RPCM Cool Vest is about 18 times less toxic than ordinary table salt. \r\n\r\nNumerous, virtually identical products are available - all petroleum-based PCM technology. Glacier Tek has introduced an environmentally responsible product that differs from every other phase change cooling vest on the market because it uses a completely non-toxic, food-based product that is not hazardous like the old-style hydrocarbon-based PCM's -- completely harmless to people, animals, and the environment. \r\n\r\n
