Cheek Pad Sizes Can be used to Provide a more Custom Fit for Your Helmet.
to provide a tighter fit in the sides of the helmet, you will want a thicker cheek pad size, so a smaller pad size than the helmet size.
to provide a looser fit in the sides of the helmet, you will want a thinner cheek pad size, so a larger pad size than the helmet size.
*Remember over time cheek pads will compress and become thinner, if the helmet fit well originally and feels looser than you may just need a new set of the same size cheek pads.
