Full-face helmets provide more protection for the face and jaw in the event of a crash, making them better for more aggressive and high-speed cycling such as downhill mountain biking or BMX racing. However, for general cycling, half-shell helmets are often preferred due to their lighter weight, better ventilation, and less restrictive feel. The choice between the two depends on the type of cycling and the level of risk involved. **

MTR helmets are a type of protective headgear designed for use in mountain biking and other extreme sports.
