This is the perfect choice for those looking for a high quality and stylish motocross, bike or offroad gear combo at an affordable price. The helmet is DOT certified. Lightweight ABS composite shell provides a balanced combination of mechanical toughness, good dimensional stability and heat-resistant. Internal polystyrene protective liner. Ventilation system for optimum circulation. The reliable and tested double D-ring system ensures stability, safety and resistance. The special shape and construction featuring differentiated density increases mechanical resistance in the event of accidental shocks. Please measure for size. Circumference of the largest part of your head, usually just above the eyebrows, or at whatever point gives the largest possible measurement. SIZE SMALL: 20.5-21.5 inches(52-55cm); MEDIUM: 21.5-22 inches(55-56cm); LARGE: 22.4-22.8 inches (57-58cm); XL: 23-23.5 inches(59-60cm). We suggest you choose a one-size-larger size, as all of the off-road helmets are a little bit tight than standard size when they are designed. For example: if your head circumference is 22 inches and is meant to choose "M" size according to the size table, we suggest you choose "L". You will be more comfortable wearing a one-size-larger helmet. Thanks.
