The Sparco Ice Vest was originally developed for Sparco’s professional drivers in Formula 1 and Indycar. The Ice Vest is designed to be used before and after racing. Cooling the body core temperature before driving has proven to help driver performance. The vest uses eight reusable medical grade ice packs placed strategically. It also has internal mesh pockets for maximum cold transfer and a waterproof membrane. The medical ice packs are non-allergenic and reusable.
