The Rapha Core Jersey is a traditional cycling jersey and is made of a stretch polyester fabrics to keep us cool and comfortable on mild to hot days. A drop-tail design provides extra coverage on the riding position, and a hem gripper keeps our jersey from moving around. Raglan sleeves and stretchy side panels are comfortable and allow for on-bike freedom of movement. The full-length zip allows us to customize our ventilation, and strategically placed shoulder seams prevent fabric bunching under the arms. Three rear pockets give us room to take along the ride essentials, and a super soft collar and cuffs give us comfort on long rides.
