David C.wrote a review of Castelli Aero Race 4.1 Solid Full-Zip Jersey - Men's on July 26, 2019
At 5'10," and 185 lbs of mostly muscle (31 inch waist, 43 inch chest), this jersey is skin-tight, which is odd, as I always wear medium-sized shirts. It's nearly impossible to zip, and the sleeves compress my arms uncomfortably. Otherwise, the jersey is awesome! I'm going to return my Large and get an XL.
