Visco-elastic foam sewn into cool, washable wear-resistant fabric. Eliminates top-of-head hot spots. Self-wicking fabric controls heat buildup by evaporative cooling of perspiration. Eliminates "bob and roll" when mounting external equipment. Lighter weight than other liners. Installation only takes a few minutes. Testing shows these helmet liners reduce skin temperature 1.5°F compared to existing liner systems. |
