This Head Strap Assembly consists of two head pads, one to fit on top of a head, and the other to be placed at the back of the head; 2 elastic nylon strings that connect with the head pads on one side and join with a buckle with each other at the other side.

To connect the Head Strap Assembly to an AYO MA mask assembly, each strap will be put through the opening between the air arm at each side of the mask and the mask cushion.

The two straps can be adjusted at the back of the neck to secure the mask on the face.
