1. A face mask assembly configured with a drop down feature, the face mask assembly comprising:
a face mask component slidable along a length of at least a first strap, wherein the face mask component comprises a first dynamic strap engagement feature as an aperture passing through the face mask component between an exterior surface and an interior surface of the face mask component, wherein the first dynamic strap engagement feature is configured to engage the first strap, wherein the first dynamic strap engagement feature is characterized by an overall width extending between a first side edge and a second side edge, wherein the first dynamic strap engagement feature defines a slide portion and a locking portion, the slide portion being characterized by a first width defined between the first side edge and a transition point and the locking portion being characterized by a second width defined between the transition point and the second side edge, wherein the slide portion has an opening height wider than an opening height of the locking portion;
wherein the slide portion comprises a smooth strap engagement edge provided along at least a portion of the first width such that the face mask component is slidable along the length of the first strap while the first strap is positioned within the slide portion,
wherein the locking portion comprises a sharp strap engagement edge provided along at least a portion of the second width, the sharp strap engagement edge being configured to provide frictional restriction to the first strap during operation such that face mask component is locked relative to the length of the first strap while the first strap is positioned within the locking portion; and
wherein a first radius of curvature of a top edge of the slide portion is larger than a second radius of curvature of the locking portion.
