The wind is howling, the snow is swirling, and yet, you keep pressing onward and upward to the summit thanks to the Patagonia Galvanized Jacket. Fortified for winter's worst, the 3-layer, waterproof, breathable H2No Performance Shell repels water, snow, and wind, while the jersey knit backer wicks moisture to keep you dry and warm in mountainous terrain. When the ascent gets really strenuous, underarm vents open to dump excess heat to keep you dry and comfortable. Covering all aspects of comfort, not just temperature control, an engineered pattern that eliminates seams from the shoulders and back gives you unprecedented freedom of movement when lifting that ice-ax or reaching for your next hold. With that ice ax in hand, you can easily adjust both the helmet-compatible hood and hem with the other hand. You can even grab snacks on the fly with convenient, watertight, high hand pockets without stopping the expedition to take off a pack or harness.
