The Patagonia R1 Air Pullover (Men’s) is a next-generation technical fleece midlayer engineered to deliver exceptional breathability, moisture management, and thermal regulation across high-output outdoor activities. Designed for movement, this pullover uses Patagonia’s innovative Air® yarn and construction to maximize airflow while still offering light warmth and agility — making it ideal for aerobic pursuits where traditional fleeces can overheat. Built with a hybrid knit structure combining Patagonia’s Air® yarns with strategic Polartec® Power Grid® zones, the R1 Air grants unmatched ventilation without sacrificing core warmth. The open weave knit across high-sweat zones encourages rapid moisture evaporation, while targeted denser knitting helps trap heat where needed. The result is a layer that feels more like a performance fabric than a typical fleece — light, airy, and ready to keep you going. A quarter-length front zipper and mock neck provide quick ventilation when temperatures rise, while articulated patterning and stretch allow unrestricted movement during activities like fast hiking, climbing, trail running, and ski touring. The regular athletic fit layers comfortably beneath shells or over base layers, and low-profile construction minimizes bulk without compromising comfort. Whether you’re pushing the pace on trail, grinding uphill, or transitioning between cold and warm microclimates, the Patagonia R1 Air Pullover is built to balance warmth, airflow, and mobility for demanding outdoor use.
