Dynafit designed the Men's Borax 2.0 Primaloft Jacket to be ultralight for fast skiing. Its Pertex Quantum fabric is surprisingly strong for its weight, with substantial windproof and water-resistance thanks to the DWR coating. Gold insulation is Primaloft's performance benchmark, offering superior softness, exceptional water resistance, and breathable comfort for hardworking skiers like yourself. When the sun warms you up, the Borax 2.0 stows inside its own pocket for compact convenience. The elements are kept out by an adjustable hood, a drawcord at the hem, and elasticized cuffs.
