Extremely light and packable, the Patagonia R1 Air Zip-Neck Fleece is built with hollow-core yarns and a lofted zig-zag texture to trap air, move moisture, and provide exceptional breathability for warmth without the weight. Perfect for high-exertion, non-stop activities in cold conditions, this fleece keeps you warm without slowing you down.
Made from recycled polyester with a hollow-core construction, the R1 Air boasts a clean, athletic design that makes layering a breeze. Light, airy, and soft on the skin, it can also be worn as a stand-alone top when the weather allows. The half zip-neck design ensures easy venting, while off-shoulder seams sit comfortably under pack straps. The simple cuff and hem design features quick-drying binding for added wrist comfort, and the left-chest pocket is perfect for stashing small essentials. With HeiQ Fresh durable odour control, this fleece ensures you stay fresh and comfortable, even at the end of a long day on the trails.
