NEW UTMB® WORLD SERIES COLLECTION
BUFF® x UTMB® – United by the Trail
BUFF® is proud to be an official partner of UTMB® World Series, the ultimate celebration of trail running and human endurance. Our shared passion for the outdoors, innovation, and pushing limits is what makes this partnership so meaningful. As the UTMB® World Series Final returns to Chamonix in 2025, BUFF® will be there — on the trails, at the expo, and in the heart of the action. We’re bringing the BUFF® UTMB® Collection: performance gear designed for trail runners, ultra athletes, and adventurers who live for the challenge.
HOKA UTMB® Mont-Blanc is more than the world’s most iconic trail running race — it’s where endurance, passion, and the global trail running community unite in Chamonix.
For BUFF®, it’s the perfect stage to present our UTMB® Collection of performance gear, built for athletes who push their limits in the mountains.
We stand alongside runners who embrace the challenge, celebrate the trail, and inspire us every step of the way.

We’ll be at HOKA UTMB® Mont-Blanc, from the event village to the mountain trails across France, Italy, and Switzerland. Visit us to discover the BUFF® UTMB® Collection and connect with the trail running community.
This year, we’re launching our first-ever BUFF® Performance Running Socks — designed for trail and ultra runners with breathable fabrics, strategic cushioning, and seamless comfort for every kilometre.
And there’s no better place to present them than in Chamonix, the heart of trail running. Discover the BUFF® Running Socks Collection and get ready for your next adventure.
We’re kicking off the BUFF® Run Club Van Tour right here at HOKA UTMB® Mont-Blanc — then hitting the road for a high-energy journey through nine European cities. From Milan to Barcelona, we’ll be connecting with urban runners through community runs, live DJ sets, and unforgettable moments on the move.
Run, dance, connect — and be part of the BUFF® running community.
