With each helmet, we supply the skull and cheek pads in order to create the two possible sizes. So, if your size straddles XS and S, M and L, or XL and XXL, you can find a VELDT helmet that fits you perfectly. Feel free to remove or swap padding, in order to strike that perfect balance between comfort and support. Changing and removing pads allows you to tailor the interior fit to perfectly match the unique shape of your head. cheek pads must be worn at all times to guarantee safety.
