Hockey helmet

The shell of a hockey helmet is generally made of a substance called vinyl nitrile that disperses force from the point of contact, while the liner may be made of either vinyl nitrile foam, expanded polypropylene foam, or other material to absorb the energy, to reduce the chances of concussion.

On older models, the helmet size is adjusted by loosening the screws on the side to slide the front portion forward or back.

[5] The hockey visor was first invented by Kenneth William Clay when he lost vision in his left eye to a high stick while playing for the Vanderhoof Bears.

While the original shield and helmet were lost in the fire that consumed the Vanderhoof Arena a few years later, the newspaper clippings still attest to the dates and facts.

[6] A cage in ice hockey is a device attached to the front of a helmet to reduce potential of injury to the face.

It consists of a metal or composite mesh that covers the entire face, although some half cages do exist (to protect the eyes while allowing full airflow).

[12] The first player to regularly wear a helmet for protective purposes was George Owen, who played for the Boston Bruins in 1928–29.

Most Bruins players didn't wear the helmet after the game, with the exception of Eddie Shore, who wore it the rest of his career.
