COOLSHIRT Systems® introduces its new DRAGPACK System to help drivers go straight faster! Designed for Drag racers specifically, this complete kit comes with the newly designed DRAGPACK ice based cooler system, a Driver Cooling Vest, an 8 ft insulated hose, and a 7 hr. lithium battery with charger. Reaction times alone can be reduced by as much as 20% with only a 2% loss in hydration. The DRAGPACK system covers 30-40% of the body with cold water circulating through tubing designed to dissipate heat away from the body, in-turn, cooling the core.
