Mammut Bionic Mythos HMS Carabiner
The Bionic Mythos HMS carabiner is light! It is smaller than most other carabiners and it is even somewhat flat. I use these all the time when I go canyoneering and I love them because I just can’t believe how little they weigh. The downside, ironically, is also the carabiner’s size. When compared to a Black Diamond Rocklock carabiner, the Mammut bionic Mythos looks tiny. It can cause some frustration if you are using larger ropes for rappelling. But overall, I am very pleased with the Mythos carabiners and plan to get more.
Retails for around $10-15
Small, lightweight and even a little flat
Small. Not so good for thicker ropes.
