How to Choose Carabiners

Extra-lightweight and compact, these Mammut carabiners have a D-shape for easy handling. The keylock nose prevents snagging when clipping. The screw-lock gate is a good choice for icy or dirty routes.

These are awesome. I bought them as the first step in building my rack, along with some non lockers. Frankly, I could have just bought these and been happy. They're perfectly easy to operate with one hand (yes, including the locking) and add that all-important peace-of-mind that can be hard to hold onto in the mountains. Love them for anchors, belaying, rappelling, and hauling!
I would love to replace all my lockers with Mammut lockers, but that seems unreasonable. Every locker they’ve designed recently has the weight of popcorn. It’s easier to make the decision to carry extra lockers for that reason when working. Of course, can’t complain about the visual unlock cue for beginners or keeping vets humble.
Recently used the carabiners on a climbing trip up in Tahoe. Worked well with my PAS and multipitch anchor. Recommend 100%.
