Page "Motorcycle helmet" Paragraph 15

A hybrid between full face and open face helmets for street use is the modular or " flip-up " helmet, also sometimes termed " convertible " or " flip-face ".

When fully assembled and closed, they resemble full face helmets by bearing a chin bar for absorbing face impacts.

Its chin bar may be pivoted upwards ( or, in some cases, may be removed ) by a special lever to allow access to most of the face, as in an open face helmet.

The rider may thus eat, drink or have a conversation without unfastening the chinstrap and removing the helmet, making them popular among motor officers.
