About the Patagonia R1 Air Full - Zip Hoody Built for layering, the feature-packed Patagonia R1 Air Full-Zip is a moisture-wicking, quick-drying, packable fleece jacket designed to keep you warm in cold conditions. Made with 100% recycled polyester, the R1's lightweight hollow core construction with a lofted zigzag texture provides exceptional warmth without weight, trapping air whilst moving moisture away from the body to keep you comfortable, warm, and dry. An athletic slim-fit design with a full zip opening makes the R1 perfect for layering and fits comfortably under outer jackets. The full zip feature allows easy venting whilst off-shoulder seams sit comfortably under a pack for lasting comfort on high-exertion cold weather adventures. For added comfort, quick-drying binding on the back hem and cuffs allows for the R1 to sit securely for the whole day. Finished with a zipped chest pocket, perfect for storing your small essentials, the R1 Air Full-Zip fleece is the ideal cold-weather layering piece or a stand-alone top in warmer climates.
