A definite addition to our range of high-performance accessories, the Ice Bob cap is designed for intense racing in the most extreme conditions. With its fashionable, protective fit and enhanced cooling properties, this innovative cap is your ideal companion, from the Marathon des Sables to the Ironman World Championships. The Ice Bob is made from ultra-lightweight, ventilated ripstop fabric that wicks moisture quickly and doesn't feel heavy or waterlogged. It has a button at the back for easy adjustment and fits comfortably without pressure points. As you may have guessed, the Ice Bob features an almost invisible pocket on the back of the head, ready to be filled with ice cubes to help regulate your body temperature as the intensity and mercury rise. As with the Ice Cap, this mesh pocket is elastic and comfortable; its contents don't bounce around and stay securely in place even on rocky terrain. With its one-size-fits-all design and flared base, this cool white running cap offers full sun protection for your head to help you stay cool and focused all the way to the finish line.
