Built lighter, with more ergonomics.
Consider Mammut's Bionic Carabiner an artificial extension of your own climber hands, gifting you the ability to clip faster and easier. Its curved spine offers extra ergonomics when you're in a hurry to climb past cruxes at the sport crag, and there are five ridges to give a subtle thumb grip. The carabiner's wire gate complements Mammut's Hot Forged construction, which rids excess materials without hindering the carabiner's overall strength, for a lighter weight suitable for alpinists.

Great for my Keys
- Familiarity: I've used it several times
So normally this biener is used for alpine draws and I would say that it is super lightweight and would be great for that purpose. But I needed a new biener for my keys and this also does really great for that.
