Polar Products lightweight CoolOR vest system keeps surgeons cool and comfortable by continuously circulating cold water from an attached cooling reservoir through over 50 feet of tubing sewn within the vest. Quick disconnect, dry couplings allow the surgeon freedom of movement as needed. Variable Flow Control enables staff to effectively manage the vest temperature. The Rechargeable Lithium Ion Battery Pack can power the unit for over six hours. All electrical components are UL listed. Neoprene gasket seal, high-density insulation and stainless steel compression latches ensure a leak proof cooling reservoir. Three vest styles and three cooler sizes to choose from for optimum comfort.
