James D.wrote a review of Castelli Aero Race 5.1 Full Zip Jersey - Men's on May 21, 2017
Familiarity: I returned this product before using it
Fit: Runs small
My first jersey was a Castelli. Love it still. I have others and while I know I need to step up a size when ordering Castelli, this jersey was particularly small. I can't say much on performance of this jersey because I never used it. I chose the 3 stars for a "middle of the road" approach. I recommend you go 2 sizes over. The XXL was so small I didn't dare zip it up. I have XL and XXL jerseys based on manufacturer, but this one is real small.
