Helmet Size Recommendations
The guides below offer size suggestion by brand based on head circumference. To measure your head circumference, place the tape measure slightly above the ear and bring it across the mid forehead completely circling the head about 1 inch above the eyebrows. Take several measurements to make sure you have the largest size. If you do not have a tape measure, use a string and measure it against a ruler. The charts below will assist you on which size is the best helmet fit. If a measurement falls in between a size, go up to the larger size.
