Reduce Core Body Temperature Fast!

The Australian designed and patented hand and forearm water immersion product cools core body temperature fast, to reduce heat stress and speed up recovery.

Combating heat stress is easy with the only small, compact, low cost and portable arm immersion cooling product on the market. Studies have found that forearm immersion in temperate water is more effective in lowering core body temperature than passive cooling, mist sprays or cooling vests.

The patented Harcor Arm Cooler Harness has been designed and developed by Fire Fighters for Fire Fighters originally and is now being introduced to the Sport and Medical market. The small and compact design of the Harcor Arm Cooler Harness means that the user can reduce their core body temperature almost anywhere, at a staging area, on the fire ground, in any urban or rural situation.

Harcor 's "Arm Core Cooler Harness" Wins the 2014 Fire Awareness award in the product design category.
