Gary Zhenwrote a review of Castelli Imprevisto Nano Jersey - Short Sleeve - Men's on April 21, 2018
This is a race fit jersey. It will run smaller/ shorter and fit tighter all around from torso to jersey sleeve. If you are unsure about your size, size up a size.
Otherwise, quality and workmanship is on point with what to expect from such a reputable performance cycling apparel brand such as Castelli.
There should be more color options though.
