The Alpine Jersey is constructed from USA-made Polartec® Powerdry Net Mesh, an open-knit fabric that creates an air gap between skin and material to improve ventilation and reduce cling during sustained effort. It functions across a wide temperature range as a standalone piece or as a breathable base when paired with a shell, making it practical for cold starts, long climbs, and variable conditions. Designed and built in Colorado from domestic materials, it prioritizes freedom of movement over a trimmed athletic fit, sitting closer to scrambling terrain than to a cycling kit.
