wondering if anyone can enlighten me. THe cluster mask has a long skinny tube that hooks to the small little nipple and the hose hooks to the output of the regulator. THen there is this other tube with a lip at the end of it. What is that? Does that hook to anything or is that some sort of release for when you are exhaling?
