4 letters: U T M B.
What started around Mont Blanc became the ultimate reference in trail running.
But ultra-distance is about more than distance. Sooner or later, the light fades. The temperature shifts. The race changes.
Those are the hours that inspired the BUFF® x UTMB World Series 2026 Collection: the unseen ones, where the body is pushed further, the mountain feels quieter, and every choice matters more.
Fluorescent tones cut through the darkness not to stand out, but to guide you forward.
