Mammut Classic HMS Carabiner

The pear shape, also known as an HMS design, provides a wide, rounded basket that allows for smooth rope movement. It is specifically optimized for belaying with an Italian hitch or managing multiple ropes at an anchor station.

The orange marking is located on the gate mechanism. When the screwgate is not fully locked, the orange color remains visible, giving you an immediate visual cue that the carabiner is not secure.

This carabiner is designed to be reliable in harsh environments. The screw-locking mechanism is engineered to operate smoothly even when exposed to dirt, grit, or ice, making it a solid choice for alpine climbing.

Yes, the key-lock nose design removes the small hook found on traditional carabiners. This prevents the carabiner from snagging on your harness gear loops, rope, or slings when you are clipping or unclipping.

Absolutely. The HMS shape is the industry standard for belay devices, as it provides enough space for the device to pivot freely and ensures the rope feeds through without binding.
