Since I redesigned my external air rig to work better with a back-mounted tank (currently have the tank in a hydration carrier and the regulator in a magazine pouch with remote hoses on either end), I've been giving serious thought as to how to use my rig without using the plate carrier.
My current idea requires an assault pack with MOLLE webbing on the shoulder straps. I need to put a pistol mag there that the regulator will go in, and I'm hoping for one that has enough room for 2-3 20oz tanks (there's an idea I've been kicking around that involves running several CO2 tanks in parallel; I'd imagine a 3-day pack would probably fit the bill). Color doesn't matter as long as it"s not black (I'll take Multicam pattern'd if available).
Thanks for the assist.
