Abstract
A respiratorthat includes a harnessand a mask body. The harnesshas one or more strapsand a head cradlethat is joined to the one or more strapsand that includes first and second laterally-extending membersand a latch. The latchis able to secure the laterally-extending membersin a spaced apart first open position to allow for placement on a person's head and is able to disengage so that the memberscan move to a second collapsed position to allow for off-the-face storage. The harness is beneficial in that it can be quickly removed from the wearer's head and can be conveniently disposed behind the wearer's neck when the wearer wants to temporarily displace the mask body from their face.
