O.M.O.H.:Well if its kicked out of your month you have to start exhaling anyway J.
I made a necklace out of surgical tubing and then I used a zip-tie to attach it to the regulator flange over the existing zip-tie that holds the mouthpiece in place. Then I tied off the ends of tubing to secure the necklace in place. (Did that make any sense?)
Cheers.
Why do you need to exhale? If you arn't rising then keep that gas in your lungs where it might do some good.
What happens if someone comes up to you and tries to grab that primary out of your mouth?
