The Coolshirt Cool-A-Clava literally keeps your head cool under pressure! This helmet insert is superior to any current air- or water-based head cooling unit on the market. The Coolshirt Cool-A-Clava plugs in to any current CoolShirt cooler or bag system. The Coolshirt Cool-A-Clava requires no special hardware and can be used with nearly every helmet available! Last but not least, the CoolShirt Cool-A-Clava eliminates the need to install a separate helmet blower system. That's less drain on your electrical system, less hose routing, less weight and less chances for equipment failure.
This product is, without a doubt, a must-have to stay hydrated and focused while on track.
