Will Moss started as a gym climber and indoor competitor in New York City and then moved on to further advance his climbing skills on the notoriously runout trad routes of the Gunks, one of the oldest climbing areas in the United States. Nowadays, Will is a fixture on the big walls of Yosemite, where he became the first person to flash El Capitan in a day, completing the Free Rider route (5.12d/13a, 3,000ft) in under 24 hours in May of 2025. When not climbing big walls, he is pursuing a mechanical engineering degree from the University of Colorado.

Joining the Vibram team with big goals for 2026 and beyond, Will brings a relentless pursuit to take his climbing to the next level and push the boundaries of the sport.
