The upper expression of our long-distance system. Engineered for when every gram matters, when heat builds fastest.Race-day essential. Training-day revelation. Pin your bib through the laser perforations without fuss. For the days you chase time. Or when it tries to chase you.

Our micro jersey fabric is knitted and perforated in Italy. It naturally stretches in every direction following the body's movements while staying breathable. It's created using a laser micro perforation technique called punch-out, which removes portions of fabric leaving micro-holes. This allows greater breathability and lighter weight while also providing an easy way to attach your number on race day. The fabric stretches naturally to follow the body's cues and sheds heat with every stride. Cool to the touch. Fast to dry.
