Does not freeze

I've put it through the wringer

A perfect choice for winter climbing. I dont know how many times I have rappelled without locking my carabiner because it is froze. these take some getting used to especially with big gloves. Once you get the hang of it its a dream. No more breathing on your carabiners trying to get them to unlock. These are the only lockers on the market that do not freeze a huge advancement in the safety of winter climbing.
