C45 Helmet Sizing Chart:
The C45 Helmet is available in eight sizes across four shell sizes, providing a streamlined fit while minimizing overall helmet bulk and weight.

Achieving the correct helmet fit is essential for comfort, protection, and performance. The C45 Helmet is available in eight sizes across four shell sizes to provide a lightweight, low-profile fit for a wide range of head shapes. Use the sizing chart to match your head circumference to the appropriate helmet size, then fine tune the fit using interchangeable cheek pads available in multiple thicknesses. For the best results, carefully measure both your head circumference and maximum face circumference before selecting your helmet size. If your measurement falls between sizes, we recommend choosing the larger size and adjusting the fit with alternative cheek pads as required.
