Built to go big. The Aspect Pro is built for missions to the Hulk, big days in the Valley, and high alpine peaks.
At BD, our passion for innovation is only matched by our desire to use our equipment and experience the success it was designed for. From the world’s first wire-gate carabiner to our cornerstone Camalots, we have always designed gear that enables climbers to push the limits of our sport.
You can't tell the history of climbing and mountain sports without telling the history of Black Diamond.
