Rodrigo M.wrote a review of Castelli Entrata 3 Full-Zip Jersey - Men's on August 6, 2019
Familiarity: I've used it several times
Fit: Runs small
Bought these during the TdF sale. Totally worth it. Followed the size chart on CC which meant I went up one size (usually wear a M in USA shirts, went up to a L here). Very form fitting and flattering. I'm not "cut", but not obese either, could stand to shave off a few pounds in the midsection. These are flattering, I don't look or feel like an overstuffed sausage like I feared. Once I get about 1.5" off my waist as I'm aiming to do...I should look really great in these.
I'm choosing "Runs Small" because a L here is a M in the U.S., but if you use the size chart, it runs true to that.
