Men mask is not so heavy.

Men is a kind of protector for one's head.
In these years, duralumine or titan are used for face fitting metal. So it is not so heavy.

A new Men/Omen, this head mask is so hard that my both ears have been painful during practice. After practice, it will become heavy for being wet for perspiration.
We hit Men, this head mask many times with bamboo sword, and hitting part of bamboo sword will be broken. By hit, someone become to be excited. It means he is defeated when he lose his control.
