For a layer that looks like a flannel but provides all the qualities and technology of a snow jacket, check out the Under Armour Alpinlite Shacket. This shirt/jacket is insulated with ultra warm PrimaLoft® synthetic insulation and incorporates UA's ColdGear® Infrared printing on the interior that targets, traps, and retains your body heat for warmth that lasts all day. With a full zip front, snap storm flap, and secure hand pockets, the Under Armour Alpinlite Shacket gives you the feel and function of a high-tech jacket with the laid-back style and swagger of a flannel.
