Mountain Bike Helmets

Mountain bike helmets are designed for the various disciplines of mountain biking. Cross Country (XC) helmets are similar to road helmets in that they’re designed to be lightweight and well-ventilated. Trail and Enduro designs offer more coverage for high-speed crash protection and a larger visor, though they often offer less ventilation than XC helmets. For downhill riding, we recommend choosing a full-face helmet (resembling a motocross helmet) or one with a detachable front chin guard, which sacrifice ventilation and lightness in exchange for an unrivalled level of head protection. See our comprehensive range of mountain bike helmets below.
