摘要

A helmet with a forward face opening and a downward neck opening comprises a hard outer shell and a custom fittable and split inner shell which fits the head of the wearer without play, is easy to put on and take off, and has a high degree of mechanical stability and provides optimal wearer comfort. For this purpose the inner shell is connectable with the outer shell and it has a fixed inner contour custom fitted to the wearer's head, a one-piece outer shell is slipped over and forms the closure for the inner shell.
