Like new used only once. This is professional level jersey. This jersey is very thin and meant for summer riding. It has 3D mesh on back to prevent overheating. Silicone gripper elastic around sleeves so sleeves stay and don't ride up.Compression band around waist keeps 3 rear pockets in place. It is size XS and will also fit size S because of the stretch. # Castelli, Shimano,Maap, Rapha,
