Gel Defenders

Our Gel Defenders are designed to aid in the protection of head injuries while using approved helmets.

While worn under a baseball cap or cowboy hat they offer some protection as well.

If you cool or heat the Gel defender before using they will retain the temperature for a period of time.

Depending on the temperature you make the Gel Defender to and depending on outside temperature comfort may last about an hour.

Some studies have been posted .
