Black Diamond athlete Chae-hyun Seo was born into the climbing life. Her parents own a climbing gym in Seoul, and by age 14, the South Korean phenom redpointed her first 9a—sending Bad Girls Club in Rifle, Colorado. Chae-hyun has also established herself as one of the top competitors on the World Cup circuit, winning the overall lead gold in 2019.
Chae-hyun still aspires to be an all-around climber, and routinely applies her champion-level skills to sport climbs and ice climbs around the world. In 2022, she climbed La Rambla—hitting the coveted 9a+ mark at just 19 years old—a glimpse of what the future holds.
"Black Diamond is a brand that has always been a dream and a sponsor that can lead the process of growing as a world climber." - Chae-hyun Seo
