This is an offering from Capo's mid-tier line and it's a good one. The jersey's intended for racing and fits rather like Castelli's aero jerseys (except that Castelli sizing is runs much smaller; an S in Capo fits like an M in Castelli). So very trim and no billowing fabric, which is exactly what you want when you're hammering, but that also means that the shirt is unforgiving of spare tires. The sleeves are just a bit longer than usual, but I don't mind. The jersey's also somewhat cropped, giving a smarter more rakish look to the kit. I've worn the black jersey on hot and humid days and managed just fine.
The one legitimate drawback to the jersey, and the reason I deducted a star, is the back pockets. While the pockets are deep, given the cropped cut the openings are high up and more difficult to access than your typical jersey. On the 40+ mile hard club rides, I like to carry small water bottles back there but I don't see how I can safely access them and put stuff back. It may be something I'll eventually get used to, but may be a cause of annoyance for those considering this jersey.
