Darren C.wrote a review of Castelli Superleggera Jacket - Men's on March 12, 2019
The size is no where near anything realistic. Ordered a "L" fits my wife who is a small/medium. I could barely get my hand thru the wrist opening and if I flexed my elbow could have blown out the sleeve at the elbow. Really disappointed as I was hoping to use it this weekend in a big bike race known for the rain showers.
This will be the last Castelli garment I look at due to their sizing issues.
