Black Diamond Oz Carabiner Review

Sometimes it's easy to get caught up in the goal for lighter and lighter gear, and forget that the gear does not just sit on a scale looking smug but will actually get out onto a climb and need to be functional. The "keychain" carabiners seem like a good party trick ("Yes these really are full-strength…") but when it comes to something you'd actually want to climb with, weight isn't the sole consideration. Black Diamond seems to have found the right mix of weight and usability with the Oz. They made it as light as they could while still keeping this product something you'd actually want to use on your cams and not just your nut tool. If you are looking for a biner that's lightweight and high-performance, our Top Pick award winner is the way to go.
