This strap is designed to add stability to the mask and prevent leaks. The strap attaches to the mask over the hose connection and then wraps around your head and connects with velcro on the side. There are 2 pieces of velcro at one end, you can cut between these to shorten the strap if necessary. There is a black strip covering over a central piece of velcro that you can remove if you want to attach it to your headgear. It was designed for the Mirage Quattro but will work on several full face masks. This is available in 2 sizes. The regular length is 31 inches and the Long is 33 inches. You can shorten either one of these by cutting between the velcro, if necessary. 


You can do a quick test to see if this will strap will help with your particular leak:

  • First loosen the straps until the mask leaks
  • With the palm of your hand against the hose connection of the mask, press the mask toward your face.
  • If that stops the leaks, then the Anti Leak strap will help.

It is a bit much to add another strap around your head, but it does work well if that is your main issue. The installation instructions are included in the package.

Do not use on a mask where it may cover the vent holes near the hose connection.
