This jersey is specifically designed for racing and high intensity training in mild Winter and cold weather (5°C-15°C) and bridges the gap between lightweight and thermal insulation.The cuff is made of pressed glue with no sewing thread, which makes the transition between fabric and skin smooth. At the same time, we bonded the hem with reflective matreial to make sure they lay flat to keep the cold air and rains out, making warm enough while riding.
