Measure the circumference of the head at a point approximately one inch above the eyebrows in front, and at a point in the back of the head that results in the largest possible measurement. Take several measurements. The largest measurement is the one you want to use. Please don't guess your size or go by the size of a previously owned helmet. Helmet manufactures vary in size.
