When we're bounding across high-elevation ridgelines and descending rocky trails through open fields, we throw on the Patagonia Wind Shield Jacket for lightweight, windproof protection. The water-resistant treatment shelters us from passing showers and fierce gusts of wind, and the Capilene Cool Lightweight lining wicks away moisture to keep us cool while we work up a sweat. Stretch panels let us move freely and increase breathability, while the HeiQ Pure odor control treatment keeps us feeling fresh no matter how many miles pass beneath our feet.
