A face mask assembly configured with a drop down feature, the face mask assembly comprising:

• a face mask configured for dynamic engagement with at least a first strap of a strap assembly such that the face mask is configured for selective movement in one or more directions along a strap length of the first strap between a donned position and a drop-down position, the face mask comprising:
• a first strap pathway comprising an exterior pathway surface positioned on a first lateral side of the face mask, the first strap pathway being configured to receive at least a portion of the first strap along the exterior pathway surface;
• and
• a strap engagement tongue defined by a material thickness extending between an exterior tongue surface and an interior tongue surface, the strap engagement tongue comprising a plurality of strap engagement teeth protruding from the interior tongue surface;
• wherein the strap engagement tongue is positioned along the first strap pathway such that the exterior tongue surface defines at least a portion of the exterior pathway surface of the first strap pathway;
• wherein the face mask is configured to be selectively adjustable between a dynamic configuration and a locked configuration relative to the first strap based at least in part on the arrangement of the first strap relative to the strap engagement tongue,
• wherein, in the locked configuration, the plurality of strap engagement teeth are configured to provide frictional resistance to the first strap to resist the movement of the face mask relative to the strap length of the first strap, and
• wherein, in the dynamic configuration, the first strap is configured to be positioned on and slide over the exterior tongue surface while the first strap is positioned on the exterior pathway surface.
