The jersey appears to be well made, but it is a bit flimsy - which is to say a little baggy with not much material support. Overall, I should have passed on this one, which I got an a fairly decent sale.
After 2 rides and 2 washes the material stretched in the back lengthwise. It was already an inch longer than all my other jerseys on arrival and bought as size Small. My cell phone in the center pocket is hanging past top of saddle. Only wear it for short rides with minimal stuff in pockets.
Perfect fit and excelent quality.
5'9" 160 lbs medium fits perfect. Great fabric also.
Excellent fit. Comfortable, with excellent wicking properties on hot days. Also, good back pockets for storing items for the ride.
Clean look. Cooling mesh. Good sleeve length. Castelli keeps making great gear.
