The new R2? Jacket is our most versatile insulation ? lightweight, compressible and warm without excess bulk for mountain pursuits. Cutting-edge routes require adaptability, which is why our R2? Jacket has become a mountain staple. It can be worn as a stand-alone jacket when you?re on the go or as an insulating layer when the mercury plummets. The stretchy and improved variegated-fiber fabric, now with a matte finish and greater warmth, has superb breathability and compressibility, along with minimal weight. Stretchy R1? fabric (now made with recycled polyester) inside the collar and cuffs enhances skin comfort, and the pliable R2 body fabric affords unrestrained movement. With a new, easy-to-use regular-coil zipper front, welded-in zippers on the pockets, and forward-set shoulder seams for pack-wearing comfort. 100% recyclable through the Common Threads Recycling Program. Trim, feminine fit.
