UTMB is the biggest global moment in trail running. For this upcoming season, our aim is to break through the visual noise with a unique partnership with the archive of renowned artist Yves Klein. The artist created a unique, vibrant hue of blue called International Klein Blue (IKB) that became a central component of his work. By outfitting our athletes in IKB from head to toe, they’ll stand out from other runners and their movement across the terrain of Mont Blanc will become an artwork in its own right. This 100% cotton short-sleeve t-shirt pays homage to the collaboration with bold artwork graphics on the front.
