Abstract
An adjustable mask provides a unique configuration, whereby one hand may be used to both doff the respirator and to securely don the mask. In one embodiment, such configuration is facilitated by a reel attached to one or cords, the cord attached at a second end to a harness designed to engage a portion of the head. Rotation of the reel in one direction causes the one or more cords to tighten, while rotation of the reel in an opposite direction causes the one or more cords to loosen.
