The U.S. Army Research Institute of Environmental Medicine tested different cooling methods to find the best way to treat soldiers suffering from heat stroke. In their October 2021 study, Army researchers compared traditional ice-soaked bed sheets with two commercial cooling products, including Polar Skin.
How Polar Skin Performed:
The Army found that Polar Skin removed heat from the body extremely well:
- Full Polar Skin System (ice sheet + four ice packs): Removed heat at a rate of 277 Watts, working as well as standard Army ice sheets
- Two Polar Skin Sheets + Ice Packs: Removed heat at 348 Watts, providing even better cooling with more coverage
- Field-Ready Design: Polar Skin sheets stay good for up to 12 hours at 100°F, making them practical for field use
What the Study Found:
Army researchers concluded that "traditional iced bed sheets and the Polar Skin device were most effective" at cooling. The study stressed that heat stroke patients need to be cooled quickly, and Polar Skin delivers the fast cooling needed to help save lives.
Other products tested didn't work nearly as well. The CAERvest only cooled at 38% of Polar Skin's power.
The Army's research proves that Polar Skin is a reliable, effective cooling system for military training and field operations where ice storage is available.
This independent military study shows Polar Skin works when it matters most—in life-threatening heat emergencies.
