One K Defender Helmet Liner
Removable washable quick-dry, moisture wicking, anti-microbial liner. Swap out for fresh new helmet feeling, or even change sizes of your helmet.
Two shells make up all sizes. The base shells for the Defender are Medium and Large. Use a Medium size helmet with a Small or XSmall liner to change the fit to Small or XSmall. Use a Large size helmet with an XLarge or XXLarge liner to change the fit to XLarge or XXLarge.
