Linerz Bump Cap Hat Inserts come in 4 different levels of protection and can be added to any hat. It is important to remember that for in order for their to be protection there needs to be room for the insert - in some cases you may have to go up a hat size to accommodate for the thickness of the insert. Once that is accomplished you will have a wonderful, customized solution for your light head protection needs.

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.

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.

Turn your favorite hat into a bump cap! 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.

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.

* 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.
