Looking for a semi-custom fit? Does your helmet fit great but is a little too tight or loose around your cheeks? Solution: cheekpads with different thicknesses. For the Ace you can interchange the cheek pads that come standard in sizes XXS-Med. For example if you purchased a Small Ace and would like thinner cheek pads, you could purchase the 30mm cheekpads that come standard in an Ace Medium helmet. You can interchange the cheekpads that come standard in sizes Lg-XXL. *The 3XL is a separate shell and the cheekpads cannot be interchanged with the other sizes.
