The Mammut Bionic HMS is a tough, super-strong belay and rigging carabiner and the sort of krab no climber should be without.
The large radius and overall size of the Bionic HMS makes it an ideal partner for a multitude of belay devices, ascenders or other rigging aids. Its size also means it will easily take a number of knots or hitches in the same rig.
Manufactured in the UK, the Mammut Bionic HMS utilises cutting edge hot forging techniques and provides I-Beam construction for improved strength to weight ratio. A smooth screw barrel and snag-free keylock nose make this premium HMS a serious contender for best in its class.
