Patagonia Women's R1 Air Jacket

The Patagonia R1 Air Jacket (Women’s) is a cutting-edge technical fleece midlayer engineered to deliver exceptional breathability, moisture management, and dynamic airflow during high-output outdoor activities. Designed by Patagonia, this jacket uses Patagonia’s innovative Air® yarns and hybrid knit architecture to maximize ventilation while still providing light warmth and stretch — ideal for aerobic pursuits where overheating and sweat buildup are concerns. The R1 Air Jacket’s construction blends open, highly breathable knit zones in high-sweat areas with strategic performance panels that trap warmth where it’s needed most. This creates a layer that behaves more like a next-generation performance fabric than a traditional fleece — offering airflow and moisture transport akin to technical baselayers with more thermal presence. The women’s-specific regular athletic fit allows comfortable layering over baselayers or under shells without bulk. A full-length front zipper lets you dial in ventilation on the move, while flat seams and articulated design enhance comfort and freedom of movement on steep trails, fast hikes, and extended ridge walks. Lightweight and agile, the Patagonia R1 Air Jacket is designed for athletes and outdoor enthusiasts who demand thermoregulation without compromise — whether on alpine approaches, trail runs, or multi-day fastpacks.
