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, a 4 or 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.
