About OTSO Sport

OTSO Sport USA

Born in the high mountains of Andorra, in the heart of the Pyrenees, OTSO Sport was created for athletes who live and breathe the outdoors. Andorra’s rugged peaks and pristine trails attract world-class cyclists, trail runners, skiers, and endurance athletes from around the globe—making it the perfect birthplace for a brand built around performance, resilience, and adventure.

Inspired by the Wolf 

“OTSO” means wolf in Basque—a symbol of strength, courage, freedom, loyalty, and endurance. These values live at the core of everything we do, and in every athlete who wears our gear.

We believe sport is not just something you do—it’s a lifestyle.
