The new Adizero head guard is the lightest full moulded head guard in its class, weighing less than 290 grams (+ -10 ounces). The head guard is designed in an innovative and ergonomic way. The holes along the top and sides enable maximum ventilation, and the density foam provides the best shock absorption. Nylon velcro straps on the back and the chin make the head guard easy to adjust for the perfect fit and comfort. Washable material allows for better hygiene. WAKO approved, this head guard is perfect for taekwondo, kickboxing as well as other combat sports.
