Glacier Tek’s vest cooling system is designed to help keep your body cool and comfortable even in the hottest and harshest environments by bringing your core temperature down. Typically, when your internal temperature rises, the body cools itself in two ways: by carrying the core heat towards the skin’s surface via the circulatory system where it’s removed as cooler air passes over the skin—also known as convective cooling—or through perspiration, also known as evaporative body cooling. But when the outside environment is too humid and/or hot to allow your body to naturally get rid of internal heat, not only are you incredibly uncomfortable, but there can be health issues associated with overheating.
Because 90 percent of the human body’s total heat is produced and held in the torso by the major organs and muscle groups, Glacier Tek’s vest cooling system decreases your core temperature when the environment doesn’t allow your body to do so naturally. By maintaining a temperature of 59℉ for up to 2.5 hours, your core stays cool enough to minimize overheating without being too cold, which can cause skin irritation and ice burns.
GlacierPacks are cooling packs powered by PureTemp, a biobased phase change material that carries the USDA Certified BioPreferredⓇ label.
Phase change materials are important in the use of Glacier Tek’s cooling vests because they provide long-lasting cooling without the potential negative effects associated with cold-induced injuries when a pack is frozen to 32℉. Additionally, GlacierPacks have been shown to accelerate recovery after eccentric exercise in recreational athletes and after games in professional soccer players.
