StaCool Vest’s Medical Cooling Vest provides core body cooling for long procedures. A thermal barrier is built in to ensure the wearer does not get too cold. This vest can be worn under clothing or as an over-vest and is lightweight, even with the ThermoPaks that are installed into it. The vests come in a wide range of sizes to accommodate any body type. These vests are not tethered to a cooling system, which allows practitioners more mobility and comfort during long surgical procedures.
