A modern mountain staple, the adaptable R2 Jacket serves as a stand-alone outer layer when you're on the go or as a superb insulating layer under a shell. Patagonia has worked with Polartec to further refine this exclusive Thermal Pro polyester fabric, now significantly lighter, more compressible and breathable, a touch warmer, and with better stretch and a softer feel. The short-sheared but high-loft face has a smoother appearance, and the directional knit wicks superbly, speeding dry times. Newly added warm stretch panels (Polartec Power Stretch) down the outer forearms and along the sides improve high-wear-area durability and allow for a closer, more mobile fit. With a softly lined inner collar and chin flap for skin comfort, offset shoulder yokes to stay clear of pack straps, and zippered pockets (one chest and two handwarmers). Recyclable through the Common Threads Recycling Program.
