The Club Systems come in two sizes, the CLUB-12 (14"L x 9"W x 11"H) and the CLUB-24 (15"L x 10"W x 13"H). Using the leak-proof Platinum Series Cooling Unit and insulated hose, the CLUB-24 System offers superior cooling for up to 6+ hours. The compact CLUB-12 SYSTEM provides the same cooling power in a smaller, compact system for those racing applications that have limited space or shorter duration races, cooling for 3+ hours.
