The AirForLife® holster is custom designed and manufactured to fit the aluminium 22 litre capacity canister. The mesh weave design and material, from which it is manufactured, was selected for both anti-slip and strength properties. Fluorescent yellow was chosen for ease of visibility by rescuers. There is a plastic-covered slot which allows users to view the instructions and other information printed on the canister. The strap is adjustable and is designed to be worn over the shoulder with the canister suspended ‘cross-body style’.
