I really like the quality of this jersey. The material is quite comfortable and I haven't put it to a true test yet, but feels very lightweight and breathable. I found the design to be good with the sleeves a comfortable length. The fit will work better for some than others - it's a slim fit but not a second-skin race fit like some of Castelli's jerseys. As typical with Castelli I found the length a bit short - it works ok with bibs but I would have preferred another inch or so in back for my tall frame.

Castelli is now catering to the growing percentage of the overweight and obese. Fit in the shoulder and upper chest area was OK but below that this jersey is an absolute tent. I'm a large in Castelli jerseys, I own 8 others and they all fit the same, which I can honestly describe as "perfect": comfortable but skin hugging, very aero. This one is out in left field. Maybe it's a manufacturing defect but I don't think so. After some searching I found a picture of the jersey on a model, sure enough there are noticeable wrinkles in the jersey around his mid section, and he wasn't rail thin. If Castelli is starting a "big mens" line of clothing I really think they should have labeled this as such.
