As you might know I have a huge underwater fetish in addition to my love of gas masks and rebreather bags... It only seemed natural for me to try combining the two. Now for the time being I only have access to a tub, but I dream of one day trying this in a pool or better yet, in open water! Frankly the tub just isn't deep enough to give me the satisfaction of full immersion, however it still feels quite nice, what a treat!
