The Oxygen has been designed with a traditional safe and solid, bent or straight gates to suit those who either don't want wires or want the convenience of this 'no-hook' nose at a more down to earth price than the Helium. Obviously, the advantage of the Clean-lock no-hook nose is the same as on the Helium, ropes slings and wires are much easier to unclip from one off these units, and these biners are much easier to slide off your rack. The Oxygen has also been designed to be a super strong unit and it certainly makes the grade with figures of 26 / 8 / 9 meaning you can choose it with confidence as a great all rounder with a bombproof finish.
