The MPR (Multi Purpose Rebreather) is a compact chestmount mCCR which features a low-profile counterung bag that is positioned on the chest, and accommodates the 1.5kg scrubber canister and counterlungs. A carbon fibre or steel oxygen cylinder can be strapped to a stainless steel plate that is located on the underside of the counterlung bag. The entire assembly is held in position using a neck strap and 5mm bungee cord between the MPR bag and the harness.
