A protective hat placed over a person's head to protect their skull. Helmets are used for multiple occasions. From the Bronze age of the Romans who used helmets as protection against arrows or even blows from swords, to the present eras of modern history such as WWI and WWII as well as modern day militia standards of protecting and preventing bullet penetration against the skull. It is usually heavily padded enough to be light weight but to provide substantial protection. In sport's terms, it is normally plastic or leather and is used to protect the head against impacts from a ball or impact with another person.
If it wasn't for John's helmet in the football game, his head would be pulp.

My dad hated Helmet with a passion. I don’t know why so many people hate this band. I guess they don’t understand them.

This isn’t a band for singer-songwriter music. And the vocals don’t really intend to impress you. But it is more about the music.
People are always telling me they don’t like the band Helmet.
