Power-up your protection! The GameBreaker Stealth Helmet Liner is discreet, supplemental padding that can be inserted into any full coverage hard shell helmet, with no modifications to the helmet needed. Exclusively made from D3O smart molecule foam, the same industry leading material that powers the 5-Star rated GameBreaker-PRO headgear.
The GameBreaker Stealth Liner is unlike any other helmet insert out there. Made from D3O, a light weight rate sensitive foam that provides dynamic protection and attenuates the transferred force of impacts without added rebound by “tensing up” when force is applied. This provides a unique blend of light-weight comfort, flexibility, and strength that is unmatched by competitors.
