Working in hot climates, particularly for long periods, is physically stressful and can compromise a person’s safety, focus and efficiency. DS Kool minimizes the effects of environmental extremes and related heat stress by cooling the body and providing chilled drinking water to the user with the DS Kool Suit. <br><br> Consisting of a tubing-lined garment connected to cooling backpack, the DS Kool Suit is easy to don and comfortable to wear. It is a conductive cooling system that effectively removes body heat by circulating cold water through the garment. The backpack contains the cooling medium which absorbs the body heat coming the garment and returns cooled water back to the garment. <br><br> DS Kool has been tested by US Military to be highly effective at maintaining the user’s body temperature at safe levels and for longer periods than any other self-contained cooling system available.
