About Black Diamond

At Black Diamond it's all about climbing and skiing. They share the same experiences that you do on rock, ice and snow and these experiences push them to make the best gear possible for a worldwide family of climbers and skiers. What began with a backyard anvil and a hammer has now grown into a global company with offices on three continents. Black Diamond is a company that's not just for rock climbers and skiers, but one that stands for the spirit of the sports we live, their values and goals, past, present and future. Since 1957, their innovative gear designs have set the standard in numerous areas. This is partly the result of dedication, desire and diligence on the part of an incredible team of people. It's also a product of the fact that each member of BD are climbers and skiers themselves.
