A robust, lightweight HMS carabiner with great handling: The Mammut Bionic-HMS is produced by using hot forging, which serves to minimise weight whilst maintaining optimal breaking strength. The large curve radius of the HMS carabiner makes for comfortable handling when belaying - even with double ropes and all belay devices. The Bionic HMS is available with Twist-lock Plus or screw gate. Its your choice!
The very lightweight Bionic HMS is very versatile, but great for alpine climbing in particular.
