About Cryogenx

Cryogenx are developing radical new medtech devices to enable humans to perform in the heat. Our first product, Cryosuit, is a portable, high performance body cooling device, designed to revolutionise heat stroke treatment. Cryosuit is the ice bath in your backpack. Designed to emulate ice water immersion with a fraction of the resources, Cryosuit enables life-saving treatment to be delivered in any scenario. By 2030, the effects of heat stress will cost the global economy $2.4trn a year, and heat related deaths are predicted to increase by 257%. We’re here to change that.
