John Fwrote a review of Castelli Attacco Limited Edition Jersey - Men's on September 21, 2019
Familiarity: I've used it several times
Fit: Runs small
I was looking for a jersey to handle early fall and late spring temps. Sifting through the usual surfeit of superlatives in the description didn't yield a clear temperature rating. I took a chance, ordered one of these, and lucked out. It easily handles 50-55F when coupled with a SS base layer, windstopper arm warmers, and bib shorts. The blurb enthuses that it handles hot temps well, will have to wait til next summer to see about that.
As others have said, the fit is very slightly (less than 1/4 size) looser than typical Castelli. I am an XL in everything else Castelli, and that's the right size for me in this.
The offset zipper looks a little weird but is unnoticeable while riding.
Wish it had one zipper pocket for cash/credit card.
