SMS Santini Italy Bike Cycling Jersey Zip Collar Shirt Large Yellow

This is a SMS Santini Ramuzzi Greve In Chianti Jersey Shirt. It is used but looks like it has not been worn. It is Yellow and Blue. It says 54 3XL but seems like it fits like a Large adult shirt. So maybe it is a youth version. There is a slight bit of dirt around the pocket on the back.
