With temperatures as high as 130 degrees in the cockpit of a racecar, a driver can lose up to 10 pounds of fluid during a three-hour race. Dehydration can impair a driver’s ability to concentrate and focus during long stints. The Sparco Hydration Pack will help combat the negative effects of dehydration. The Hydration Pack attaches to the back of any Sparco competition seat, along with most non-Sparco seats. It features a specially designed insulated pouch that holds 2 liters of water. The drink tube can be attached to the shoulder harness to keep it properly located for easy access, and it features extra pockets for carrying small items. $105.
