The ultimate cold-weather midlayer, The Patagonia Women's hybrid-design R2® Jacket provides exceptionally breathable, quick-drying warmth in its most compressible Regulator style. To save weight for the route, you might jettison the stove, the number 4 cam and the summit candy bar, but you’ll never leave the R2 Jacket behind. For northern latitudes, frigid starts and cold weather, the highly refined construction and fabric of this Regulator fleece traps heat and breathes freely to keep you warm and comfortable across a wide range of conditions. The main body relies on high-loft Polartec Thermal Pro recycled polyester fabric, which is superlight, wicking, compressible, stretchy and soft. R1 Polartec Power Grid™ high/low grid panels wrap each cuff and run along the underside of the arms and down the sides to improve fit, mobility and comfort range. The cuff’s spiral-seam construction won’t constrict your forearms when you push up the sleeves, the softly lined inner collar and kissing-welt zipper garage go easy on the neck and chin, sonic/stitch seam construction on all zippers reduces bulk, offset shoulder seams stay clear of pack straps, zippers close the external pockets (one chest and two handwarmers, above harness line), and the handwarmers’ pocket bags double as stealthy internal mesh drop-in pockets.
