NEW UTMB® WORLD SERIES COLLECTION
BUFF® x UTMB® World Series – Own the Night
BUFF® is proud to be an official partner of UTMB® World Series, the ultimate celebration of trail running and human endurance. As the UTMB® World Series Final returns to Chamonix in 2026, BUFF® will be there, on the trails, at the expo, and in the heart of the action. UTMB® isn’t defined by daylight, it’s shaped by what comes after. When the sun sets and the trail fades, the race becomes quieter, harder, more real, and that’s where it truly begins.
Built for the defining moments of UTMB®, when light fades and conditions shift. Fluorescent tones enhance visibility in low light, while lightweight, technical gear is designed to protect and adapt. Essential pieces that move with you, from start to summit. Because when the sun goes down, you keep going.
HOKA UTMB® Mont-Blanc is more than a race, it’s the ultimate expression of trail running.
For BUFF®, it represents everything we believe in: pushing limits, adapting to the mountains, and moving forward in any condition. It’s where our products are truly tested, in the most demanding environment, by a global community of runners who share the same mindset.
Being part of UTMB® means being present where it matters most, on the trail, in the elements, and alongside those who keep going, no matter what.
