Deadline for orders is the 1st April to allow enough time for the jerseys to be produced. Any orders after that point are not guaranteed of being fulfilled. The size guide shown is our manufacturing guide and measures the exact size of the jersey not the person wearing them, if you have a jersey that fits you well to compare to the size guide then that is the ideal otherwise I would add a small amount to any measurements of yourself unless you like skin tight jerseys. Vapore® Bio Moisture fabric is a fibre filament moisture system that supports the movement of moisture away from the skin ready to evaporate. 100% upgraded Vapore® European bio moisture fabric. The fabric is soft to the touch and comfortable. Front and rear of jersey is made of Vapore polyester blend fabric. Side panels made from upgraded Vapore mesh for additional heat dispersion. Styled for a fitted look and feel. High quality full length robust hidden zip for style and comfort. Three deep rear cargo pockets for mid ride essentials. Soft high collar for extra comfort. Full circumference silicone gripper in the hem.
