Nice Jersey. However, in my opinion this does not fit the way my other Castellis do. This is true to size. So my advice would be to not order one size up which is what most people have to do with Castelli.
It's ultra lightweight with good wind and rain protection. Fits easily into my jersey pocket. As with most European brands, I had to order one size bigger, resulting in a perfect fit. Get the black for added style points.
