The S2R combines the added protection of a full face helmet with the feel of an open face model. It is an excellent choice for all closed car forms of racing including sports car, drifting and autocross.

An effective helmet is one that fits properly. Have an assistant use a measuring tape, or a piece of string to measure the circumference of your head starting at a point approximately one inch above the eyebrows in front, around a point in the back of the head that results in the largest possible measurement, and finally wrapping back to the front. It is a good idea to take several measurements to make sure you have the largest one.
