Passo is Italian for ‘step’. We spell our passO HMS carabiner with a capital O because we feel that it’s a step ahead of the competition. It has a gigantic gate opening and is available with a screwgate, twistlock and trilock locking system. It also forms the basis for our inLock and pinchLock carabiners. The essential locker for every climber. One small step for HMS carabiners, one great leap for your climbing confidence.
