Coolshirt HotHead System

The HotHead System is designed with the budget-conscious racer in mind. The HotHead provides head cooling for those who want a small, lightweight system and don't need body cooling. The kit includes a Coolshirt Kart Bag (powered by 12V hookup or an optional lithium-ion rechargeable battery kit), a four-foot water supply hose with safety-pull release fittings, and a Coolshirt Cool-A-Clava. It's perfect for open wheel racing, legend cars, HPDE participants, and sports car racers who want cooling but don't want to add much weight or amp draw to their vehicle.

Bag Dimensions: 4 D x 7 W x 7.5 H

Race Ready Weight: 6.5 lbs

Amp Draw: less than 3 amps
