Worn as stand-alone outerwear or as an insulating layer, the stretchy and technical R2 Jacket has become a mountain staple, with good reason: The variegated-fiber fabric yields superb warmth, breathability and compressibility with minimal weight. Stretchy R1 '\\" fabric under the arms and inside the collar enhances moisture-wicking, and the pliable R2 body fabric affords unrestrained move- ment. With reverse-coil zippers throughout (welded on the chest pocket). The minimalist pullover has a deep front zipper that ventilates and allows for easy on/off. Made in USA and imported.
