Most of my cycling kit is either Capo, Castelli, Pissei, or Campagnolo (gotta love the Italians) but Capo is my favorite. This jersey is indicative of their line: very stylish, high tech fabrics, with thoughtful design. The anatomically cut panels follow your form yet allow for freedom of movement while having the added benefit of looking sharp. I tend to need a wind vest if wearing this in the 40-5F range if I'm not doing a lot of climbing but I also run cold normally. Wicks away moisture and dries quickly if you've had a good workout or get caught in some rain. The full length zipper stays locked in place allowing you to ventilate without flashing everyone which is always a plus ;) and moves smoothly enough to allow for one handed adjusting up or down. Would prefer it if there were more reflective elements for low visibility safety and a zipper pocket for keys/cellphone or whatever you don't want to pop out when grabbing for other items which why it gets only 4 instead of 5 stars. I've had mine for over a season and it still looks almost new after quite a few rides so durability almost makes me want to bump it up to 5. In terms of fit, Capo is race fit but not as snug as Campagnolo so go a size up if you want more of a club fit. I'm 5'4", 34" bust, 28" waist, 130 lbs and wear size small in Capo.
