As usual, get one size bigger with your castelli clothing.
The fit, color, and style are all fine. The fabric is a bit clammy when sweating (worst than PI Elite).
The biggest problem is the seams in the back. They are so prominent and get really itchy wearing it.
It�s unbearable for me.
After this experience, I went back to Pearl Izumi elite jerseys which are much more comfortable and cheaper.
I will stay away castelli jersey until it has flat seams.
Overall the quality and fit of the jersey is fine. I don't however care for the length of the sleeves as they tend to bunch up at my elbow. I guess on cooler days this might be a good choice if a long sleeve is not warranted. I tend to buy several colors of jerseys I like since I'm a daily rider and go thru jerseys quickly. I will not however acquire and additional color in this style.
Cycling clothing is notoriously small, but this goes beyond all others. Bought this for my husband in XL, his normal cycling apparel size L or XL. The jersey fits me, at 128 lbs, 5'3. So guys, unless you are the size of a racehorse jockey - don't waste your money.
