How to Put Holes in the Liners of Football Helmets

The inside liner of a football helmet is engineered to absorb force and protect your head in a collision. However, depending on the helmet liner’s design, the helmet may block a significant amount of air flow to your head and face, creating a stifling heat that makes staying focused on the game fairly difficult. You can punch a few holes in your helmet liner to improve airflow without negatively affecting your personal safety. Holes in the liner also allow you to run communication electronics through the helmet.

Instructions

    • 1

      Remove the foam liner from your football helmet. Liners are usually secured by simple snap buttons.

    • 2

      Examine the top of the foam for air holes. Some liners may already have holes, in which case you should avoid making modifications.

    • 3

      Check the shell of the helmet for air holes. Mark the areas on the foam liner that correspond to these air holes; if your holes line up, you will get more airflow.

    • 4

      Drill holes through the foam at each of the marked locations. Use a slow drill speed to avoid tearing the foam and make sure each hole runs all the way through.

    • 5

      Insert the foam back into the empty shell.
