Mammut Bionic Mythos HMS Carabiner

Available Colors / Styles

Basalt/Screw Gate

The Mammut Bionic Mythos HMS Carabiner's I-beam construction provides tons of strength while decreasing weight to a minimum. Its pear shape works very well for belaying and rappelling, and a large basket helps when you need to clip in to a cluttered belay point. Mammut likes to keep things simple and functional, so it stuck with a basic screw gate to make this 'biner worthy of your trust.

Bottom Line: Strong light, and still bomber.

Talk shop with all the gear freaks out there: ask 'em questions, upload/browse photos, and give your 2¢.

Wearing very Quickly

By:

Just bought this and after a week of solid use sport climbing there is already significant wear. I use a Mammut Smart belay device and that seems to hold the rope in one spot so perhaps that is part of the wear issue but there is already a groove and with the I-beam construction it has created a sharp/rough edge. My last belay biner was a DMM and it lasted for well over 2 years before developing a significant groove

HMS - Halb Mastwurf Sicherung (from German language) - it means half clove hitch belay. The sign HMS or H in a circle on a carabiner indicates that this carabiner is designed to be used with this kind of knot for belay or descending. The HMS carabiner is always locking and is generally oversized and pear-shaped one.

Halbmastwurfsicherung. Mouthful, isn't it? Also known as the Munter Hitch or the Italian Hitch, it's a link in a belay system that can be reversed with a wide enough 'biner, like this one.

Great biner. Love it in an autolocker for anchors and belays two climbers well with a reverso. Also a great sport climbing biner, and the suuuper large pear shape easily accommodates a munter hitch if your atc magically disappears or never showed up.

It's a German abbreviation for "HalbMastwurfSicherung" (=Munter hitch belay)

HMS just means that the biner is oversized and generally pear shaped and meant to be used for belaying or with a Munter hitch due to their bigger size, and it also tells you it will lock in most cases

I'm looking for another

Keeps twisting around so that it ends up sideways many times (the load is on the gate) while belaying. Otherwise, it's great...

This carabiner has a nice auto-lock mechanism that should last a while. Works great for belaying and looks cool too. Definitely a large biner

prefer the screw gate to the auto-locker, best looking biner i have found, and other than that its just another caribiner-there all the same-but this one looks sweet and im a fan of all mammut products.
