I have had a couple of 30min SCBA tanks and been thinking for sometime of making a dual range bag for them. I have plans of doing a future rifle I have coming in FDE, so got me to thinking about getting this bag made up to go along that color theme. After a little search I found some desert digital camo, and thought it would give the bag a different look from some of the others I have made, I plan on plumbing it in cascade or in parallel manner so I can draw air of both tanks at the same time.
