Dehydration can impair a drivers ability to concentrate and focus during long stints. The Sparco Rally Drink Bag will help combat the negative effects of dehydration. The Rally Drink Bag attaches to the back of any Sparco competition seat. It features a specially designed insulated pouch that holds 2 liters of water.
