Thanks to a technical blend of Warmer and Warmer X-Stretch fabrics, the Castelli Unlimited Thermal Long Sleeve Jersey manages to feel warm on a cool day, while remaining comfortable to wear if the sun comes out or you reach a tough section of the track.   The blend of weighted panels will ensure that, if you are hard on the pedals on and off the road, your temperature will be managed. The brushed fleece on the body and arms of this jersey will keep you cosy, while the side panels will allow a degree of airflow to help you stay dry.   This striking jersey is perfect for spring or autumn wear, with three pockets to hold your spares, a grippy hem to prevent it from riding up in ride position, and a faultless zipper for easy ventilation and dressing. Versatile and attractive, it can be paired with a protective vest to maximise its usefulness.   Features: With Warmer brushed fleece fabric at the body and sleeves. Warmer X-Stretch side panels ensure it fits like a glove. Keeps your core cosy on early or chilly rides, without you overheating. Gripper elastic keeps the hem firmly in place as you ride. YKK® Vislon® zipper assists with temperature control. 3 handy pockets. Weighs 241g (medium size). For use at temperatures from 14-18˚C, 57-64˚F.
