The Patagonia Men's R2 Insulated Jacket spans the spectrum of cold-weather usage. It uses Polartec® to refine this exclusive Thermal Pro® polyester fabric, which is super light, extremely compressible and breathable, warm, stretchy and soft. The short-sheared but high-loft face has a smooth appearance, and the directional knit wicks superbly, speeding dry times. Polartec Power Stretch® panels on the outer forearms and along the sides increase durability in high-wear areas and allow for a close, mobile fit while retaining warmth. With a softly lined inner collar and chin flap for skin comfort, offset shoulder seams to stay clear of pack straps and zippered pockets (one chest and two handwarmers).
