The Crosstrek™ ¼-Zip, made from Patagonia's newest fleece fabric, provides next-to-skin comfort during extended movement, durability for season after season pursuits and stretch for the full range of active motion. Beautifully crafted from Polartec® Power Stretch® fleece, it has a smooth, flat outer face that slides under outer layers. A soft, napped inner surface traps warmth and wicks moisture to keep you dry. Flat-seam stitching throughout reduces bulk and minimizes chafing under pack straps or harness. The cuff design lets you push the sleeves up your forearms for climbing; thumb loops hold the cuffs in place when you need additional warmth or coverage. With a zippered media pocket on the left chest to hold your favorite playlists.
