The 100% R-Core-X LE Long Sleeve Jersey is specifically designed and built for Downhill and Enduro racers. Having full arm coverage is critical in this type of racing, where a fall or contact with a trail feature or root or rock can mean the difference between bloodied arms or trail rash. A riding jersey is only as good as the materials that it is built on, and the R-Core Le delivers with its highest performing line of fabrics. Made with 4-way stretch materials which are a combination of Polyester and Spandex mesh fabrics, the jersey is both highly breathable, moisture wicking and lightweight. It keeps you cool during the hot dog days of summer while providing warmth and protection from cool riding temps once the season changes from summer to fall or spring to summer. Possessing moisture management and anti-microbial properties, the R-Core is both semi-permeable and odor free no matter how much you sweat. Contrast taping at the shoulder, sleeve and body hem reduce weight and supply added comfort. A drop tail provides extra coverage when you get into aggressive riding positions and helps keep dirt, water and debris from hitting your backside and entering your riding shorts. A handy internal goggle wipe keeps your eye protection clean and running clear. If you are a racer or just an aggressive trail rider looking for the highest performing apparel, then the 100% R-Core-X LE Long Sleeve Jersey will deliver for you.
