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.
