About

Linerz ball cap inserts are a layer of foam that can be added to any hat.

Turn your favorite hat into a bump cap! Our patented Linerz design offers comfort and ventilation to keep your head cool as well as maximum versatility to provide an added layer in the protection against minor bumps and bruises. We cannot guarantee our product will prevent injury but our high quality, high density foam will create an added barrier that will aid in reducing the risk of injury.

Linerz are durable and last a long time. The protective liner is removable and cleans easily with a little soap and water, let air dry.

Fits many styles of hats, baseball hats, trucker hats, cowboy hats, boonie hats, and more. You may have to go up a size or two to accommodate for our thicker Linerz Inserts.

As is the general nature of foam to degrade and lose its form over time, we suggest replacing your Linerz insert every 1 - 2 yrs based on use.

Warranty: If you decide the Linerz are not a proper fit for your industry or environment please return within 7 days for a full refund. 

Hat not included. We have specially designed Linerz hats coming soon! Stay tuned.

* Bump caps in general are not designed for use in ANSI hard hat designated areas
or for any location or movement where serious injury to the head may occur. However, they can be used inside of a helmet to offer added protection and a better fit. 

There is no US standard for bump caps or any regional or international standard that exists for bump cap products except for the EN 812 standard in Europe. Bump Caps have limited application for occupational use and are not a substitute for industrial head protection identified in the ANSI/ISEA Z89.1 standard which is codified by OSHA.
