Lovely looking and comfortable aero jersey.
Great jersey. Form fitting. I'm 167 cm and weigh about 70 kg and a medium fits snug but comfortable. I'm very happy with this purchase.
Good, I am 178cm, 80kg, Korean. L size is a little bit small to me. Aero jersey style is tight so I feel like awkward. But almost good
Sizing may not be same as other clothing, but following the size guide, it is a perfect fit. Very well ventilated to keep cool.
Being pretty small build, I got a medium. It was close to being my perfect cycling jersey. So close! My arm circumference is about 27.5cm. is just so slightly too loose. But I am sure it will be someone else's perfect cycling jersey.
Awesome race fit. My new favorite jersey. 6'0" 205 lbs and XXL is perfect.
Excellent quality and fit. Has great back pockets and looks good too.
This is my second Castelli AR 4.1 Jersey. The first jersey lasted a long time. I really like the race fit. It's a good jersey. I purchased red this time. My previous was white. I wish I could find another white one. The darker colors seem to be popular now but for me white is hard to beat.
Top piece kit. Comfortable for the long ride
