If you thought your day of boarding was cold, wait until you hit the town for some late-night festivities. Crosstrek™ Bottoms, made from Patagonia's newest fleece fabric, provide 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, they have 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 a harness. A cut-and-sew waistband lies flat against your body for increased next-to-skin comfort with pants and hipbelts. The leg tapers to the ankle to create a technical fit and features anatomical seaming for additional mobility. With a zippered pocket on the right thigh for a media player or phone.
