Black Diamond’s largest competitor is Petzl. This is true when looking at all climbing gear as well as headlamps. Petzl has made a huge name for itself over the past years. They’re a more family-centered company that operates out of France. Not only do they make great gear, but they’re also heavily involved in community efforts for social and environmental justice. Just like any other outdoor brand, who is the best often comes down to opinion. Black Diamond is well-known across the world and so is Petzl, but Black Diamond has expanded to more territory, such as skiing. All-in-all, it’s impossible to say if one is truly better than the other.
