The thermal long sleeve jersey is a snug-fitting jersey made of a moisture moving winter microfiber with a soft brushed inner surface. This loft retains heat for warmth but also breathes well enough to avoid the feeling of being too warm. This is a mid-weight jersey that has everything you need and nothing you don't. There are three rear pockets with the Giordana pocket lip to keep your valuables inside your pocket. The front uses a hidden cam-lock zipper to maintain the integrity of your artwork.
