The face mask visor is multi curvature and made of a scratch and impact resistant polycarbonate material with a flame retardant coating and provides excellent panoramic vision. The visor is held in place by two U shaped clamps. The mask will allow the wearer to wear integrated spectacle frames, without compromising the face mask seal. The mask is available with either a five-point fully adjustable neoprene strap style harness or a two-point adjustable Polyester or Kevlar™ net style harness. The face mask features a left hand side bayonet connection for the demand valve. An option of an additional right quick fit port is available to take a communications interface if required.
