From high-altitude base camps to low-down valley floors, over the years the Retro-X Jacket has logged time in some spectacularly rugged sites. It has a breathable, windproof barrier sandwiched between cozy Synchilla® polyester (86% recycled) fleece on the outside and a moisture-wicking, 100% polyester brushed-mesh lining. Quilted Supplex® nylon panels over the shoulders and collar stands; spandex binding at cuffs and hem block drafts. Wider back panel at hem creates a more ergonomic fit. A fleece-lined collar and protective wind flap prevent the chill from sneaking in. Y-Joint™ sleeves and zippered handwarmer pockets.
