Collection: Linerz Bump Cap Hat Inserts

Linerz Inserts come in two levels of protection: The LINERZ18 and the LINERZ18HS.

The LINERZ18 is a thin but protective 1/8" layer of high-quality, high-density EVA foam.

The LINERZ18HS is our original 1/8" layer of foam plus an added flexible hard-shell layer to further help protect against bumps, pokes, sharp corners, etc.
