Early mask-visor (1996)
Our designers began work on a vented mask-visor more than fourteen years ago. The early design was never put into general production, but included features that have been carried on into the current Mask-visor.
The stand-off at the top of this 1996 visor has morphed into the sunshield on the mask-visor. The clever bends allowing a vent over the mouth have become the separated mandibles on the Mask-visor allowing far better venting and speech audibility.
