How To Install

Linerz Protective Hat Inserts


The best way to install Linerz Hat Inserts is to begin with the with the largest flap facing the back of the cap. If you are using our Hard Shell insert, the foam should be facing out towards your head. Push the insert into the cap and then begin sliding the individual flaps into the brim pocket one by one in a circular direction around the crown of the hat. You can slide the flaps left and right to adjust them so they fit snugly together. Try to be sure there are no gaps between them or overlapping when you are finished.


Linerz Inserts come in one universal size. Most adjustable hats, trucker hats, etc will work well with our inserts. As we did our very best to try to accommodate everyone, sometimes depending on the style of hat and size of head, you may need to go up one hat size to allow for the size of the insert. The inserts are also trim to fit so if there is any overlap you can simply trim off any extra material for a more custom fit. When using the insert in a helmet or a hat without a gutter inside the brim, we suggest attaching it with small velcro adhesive discs for easy removal and cleaning.
