The THORZT Sub Zero Chilly Vest is designed to cool the body and assist with Heat Stress prevention by promoting the body’s thermoregulation. A cooler body also sweats less and less sweating means reduced risks of dehydration.

How Cooling Vests Work

The THORZT Sub Zero Chilly Vest contains cooling crystals that can absorb up to 500 times their weight in water. When activated (by submerging in cold water for several minutes) the cooling crystals expand and transform into gel-like substance that can maintain the temperature of the water in which it is submerged for prolonged periods of time.

Cooling Vests can be worn during physically demanding work in hot conditions, to cool the body and bring down the core temperature. Many Olympic Athletes ‘Pre-cool’ during competitions by wearing cooling vests for the full the hour before they compete. This ‘pre-cooling’ ensures optimal core temperature and hydration levels necessary for peak performance. Equally cooling vests can be worn ‘post-activity’ to cool the body and help restore the core temperature to cooler more comfortable levels.
