Mammut Bionic CrossLock Carabiner

The Mammut Bionic CrossLock is a pear/HMS locking carabiner designed for belaying with HMS-style devices. It targets climbers and belayers who use Mammut Smart or similar bucket-style belay devices and want a carabiner that resists cross-loading and keeps the device correctly oriented.

Key benefits

• Pear (HMS) profile: provides correct seating for belay devices and smooth manipulation when lowering or belaying.
• Cross-load protection: a metal swinging keeper keeps the gate aligned to reduce the chance of side-loading the carabiner.
• TwistLock Plus locking: automatic twist-to-lock action ensures the gate locks as soon as you release it during clipping.
• Hot-forged aluminium alloy: robust construction for durable, everyday climbing use.

Primarily intended for use with Mammut Smart and similar HMS belay devices, the carabiner also works for anchor building and general rigging. Suitable for rock climbing and indoor walls, used year-round depending on conditions.
