Patagonia Men's R1 Air Jacket

The Patagonia R1 Air Jacket (Men’s) is a performance-oriented, technical fleece designed to deliver exceptional breathability, moisture management, and temperature regulation across high-output outdoor pursuits. Engineered to support sustained movement in cool to cold conditions, this jacket uses Patagonia’s innovative Air® yarn technology combined with strategic knit construction to balance airflow and thermal comfort better than traditional midlayers. Designed for climbers, hikers, fastpackers, and ski tourers who generate a lot of body heat, the R1 Air Jacket features a hybrid knit structure: highly ventilated knit zones across core sweat areas merge with targeted power grid panels where warmth and next-to-skin comfort matter most. The result is a layer that breathes like a baselayer but delivers the feel and light warmth of a fleece — making it ideal for aerobic and technical pursuits where moisture buildup and overheating can be limiting. The regular athletic fit layers smoothly over base layers and under shells without bulk. A full-length front zipper allows for rapid ventilation control on the fly, and the integrated hood adds light weather protection with minimal weight. Flat seams and articulated construction enhance freedom of movement and reduce chafing under packs or harnesses. Built with performance and sustainability in mind, the R1 Air Jacket uses recycled materials and is Fair Trade Certified™ sewn — a do-everything midlayer for dynamic outdoor use.
