Eugen Euu Extremely comfortable and aerated
Jeremy If you're looking for a more durable yet still comfortable version of the climber's or aero race jersey this is it. Just like the other high end Castelli race jerseys this is a true race cut and fits tightly. Pleased to see castelli has transitioned to the larger tooth zippers, too many failed zips in the past.
Herbert Fits great, good quality, can't beat the price!
Mr AN Its tight but looks good
Mr Sahin i loved so much this jersey. fit and comp. i m 175cm 75kg i bought M
Mr Proctor Ordered this for summer conditions so had to wait a while before using it. Now that the hot weather has finally arrived I have been using this jersey a lot and I love it. It is tight fitting but the mesh material helps to keep you cool and dry. This is a very light jersey but still has three main pockets on the back with a small zipped one to keep smaller items safe. One thing to remember with this jersey is that due to the light materials used it offers far less protection from sun, so if you are out in full sun don't forget the sun block.
PC Excellent fit, ventilation and quality. And with 50% off it's just perfect. (the size choice is as recommended by the chart - I use M in other brands and L in Castelli)
Mr CANIMOGLU Anthrachite color and M size product ; my measurements chest 95 and waist 82 cm...Maybe a little small for me...Good looking and perfect aero for long rides...Good discount...Thanks
Mr MCLEESE Lovely looking and comfortable aero jersey.
Jeff Dee 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.
Chunho 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
Mr Yang Sizing may not be same as other clothing, but following the size guide, it is a perfect fit. Very well ventilated to keep cool.
Dan @ SG 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.
Mr Piper Awesome race fit. My new favorite jersey. 6'0" 205 lbs and XXL is perfect.
Mr Tuhkanen Excellent quality and fit. Has great back pockets and looks good too.
Donna 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.
Mr Haskins Top piece kit. Comfortable for the long ride
