This men’s technical jersey is made for high-output sports like ski mountaineering, climbing, and fast-paced hiking. Designed as a lightweight mid or base layer, it’s crafted from Polartec® Power Grid™ fleece, a cutting-edge fabric with a patented bi-component grid construction that regulates body temperature while allowing sweat vapor to escape efficiently. A soft build, it offers exceptional breathability and quick-drying performance without compromising on warmth or comfort. The center-front zip adds ventilation control during high exertion, making it ideal for layering in cold, aerobic environments. The style is complete with long raglan sleeves and a raised neck.
