Another great Castelli Jersey!
If you are slender(racer body), then Castelli is the brand for you. I am 6' tall and 170lbs with 31" waist and 39" chest. In Castelli I wear a size Large. I like a good tight race race fit as where my buddy of exact build prefers Castelli gear in XL but my opinion is it looks silly being slightly loose. If you have a belly really size up or buy another brand because it will show. I have almost every model of higher end Castelli jerseys and the Prima is definitely one of my top picks. Pair it up with the Body Paint 2.0 bibs and it just doesn't get any better.
