Good Morning 405th ID, I've already made a suit currently where my breathing system entails the use of a vinyl tube that has a notch in the dead center of it and bent to use to breath through, I currently do not have enough space to fit in a larger system than that (ie, a rebreather mouthpiece) to much more comfortably breath through. I'm currently in the process of making another suit/helmet and I will have a bit more space between my helmet and mouth. I also wear a balaclava to hide the neck and am unsure how to make a comfortable system to breathe through and that can stay hidden. I'm just curious what systems you guys use instead.
TL;DR: I'm making a helmet and wonder want ideas for breathing systems you use, that are comfortable and are consealed.
