Triple 8's Sweatsaver Skateboarding Helmet Replacement Liners are constructed with three super-comfy foam layers wrapped in plush fabric that wicks moisture away from the eyes and face, and helps control odor. The plush terrycloth liners attach with hook-and-loop tape and are easily removable for cleaning; wash gently by hand and air dry. Triple Eight Sweatsaver Replacement liners are available in six sizes: X-Small, Small, Medium, Large, X-Large and XX-Large.  Use the liner with same size as the corresponding  Triple 8 Sweatsaver Skateboarding Helmet to ensure correct fit.  Manufacturer..
