Edelrid Nineteen G

While it is incredibly light, this carabiner is primarily designed for alpine climbing, trad racks, and long approaches where weight savings are critical. For high-volume sport climbing where you are clipping frequently, you might prefer a slightly larger carabiner that is easier to handle with gloved or tired hands.

Because it is the lightest carabiner in the world, the profile is quite compact. It is perfectly functional, but climbers with larger hands or those wearing thick gloves may find it slightly more fiddly to clip than a standard-sized carabiner.

Yes, it is fully certified (EN 12275) and maintains a major axis strength of 20 kN, which is robust enough for anchor building. However, keep in mind that the small gate opening of 18 mm can make it tight when trying to fit multiple ropes or bulky slings through the gate.

The wire gate is generally more reliable than solid gate mechanisms in freezing temperatures because there is less surface area for ice to build up. It is an excellent choice for winter alpine objectives where gear reliability in the cold is a priority.

The primary trade-off is handling ease. To achieve the 19-gram weight, the carabiner is smaller and thinner, which means it lacks the ergonomic bulk of heavier carabiners. You are trading comfort and ease of use for significant weight reduction on your harness.
