The internationally patented X-Change system is a completely new approach to mask design; it allows the inner edge of the bib to be slotted securely into the aluminum extrusion on the mask where it is then locked in place.

• Contour Fit System
• The bib and all the padding can be removed and machine-washed.
• The lamé at the sides of the mask, which is often the first to wear out, has been completely eliminated.
• The bib can be easily replaced
• The mask is significantly lighter because there is no overlap of materials, no spring case and less welding.
