Slick Ricwrote a review of Castelli Garmin-Cervelo Team Jersey - Short Sleeve - Men's on December 20, 2011
I'm 6'1 203, and I wear the XXL. Fits perfect. Standing up it can be tight, but it relaxes and is designed for the riding position. Never any problems feeling to tight, if you are spending more time standing up then in your drops, you're doing it wrong!
