"Sport" level jersey is well made.
This jersey is from Giordana's "Sport" range and the fit is just that; snug through the arms and shoulders and a little more forgiving through the stomach and waist which should suite most riders of medium build. Fabric is lightweight but warm enough for everything but the coldest winter days.
The good: fabric and stitching are great quality. Cut is comfortable and fits well.
The bad; no silicon gripper leaves the jersey riding up as you ride, pockets are not super deep and the zipper is lightweight.
Overall a good comfortable jersey, just treat the zipper with a little care.
