A new emergency cooling vest is designed to prevent heat-related deaths without requiring electricity or refrigeration.
The lightweight ColdVest is the world’s first portable, Class 1 FDA emergency cooling device that can rapidly lower core body temperatures up to 5 degrees in under 3 minutes, according to a news release. The device uses patented endothermic cooling technology to rapidly activate internal cooling chemicals when liquid is added.
The product provides emergency cooling for military personnel, outdoor workers, athletes, and others at high risk of heat stroke before EMS personnel arrive. People suffering from heat stroke typically have 30 minutes before suffering permanent harm. In just under three minutes, ColdVest can reduce core body temperatures and stabilize an individual.
To activate, users add three liters of liquid to ColdVest’s integrated bladder. The water combines with cooling chemicals and spreads throughout the vest.
