Fit Guarantee

Use our size guide to determine the best fit for you, if you receive the helmet and it is too big or too small we will cover shipping both ways on a larger or smaller helmet!
All CP Helmets have the SIZE ADAPTING SYSTEM that allows you to dial in the helmets fit perfectly with the turn of a dial while wearing the helmet. This incredible system will allow you to adjust the size of your helmet almost one full size.

Additionally the visor can be modified with foam strips of different thickness to fully customize the fit of the visor to your face. Never before has a visor helmet been this customizable.

Fit Guarantee does not apply to sale helmets as we have limited availability in those models.
