As mentioned before, Black Diamond has the same roots as Patagonia. To say that they are related today is similar to saying that humans are related to monkeys. We came from the same ancestors, but aren’t nearly the same today. Patagonia and Black Diamond are neither owned by the same company nor are they affiliated in any way today. The only similarity is the roots in Chouinard Equipment. Patagonia came from the same place but was alongside Chouinard Equipment, rather than a part of it. Today, they have completely different missions and practices. Patagonia often encourages people to not buy their gear and is a privately owned, environmentally-focused, business.
