Large is perfect for me. Very comfortable and great race fit!

Well made, sturdy. Lightweight for the hottest days, really deep back pockets devour gels, pump, tools, phone. Very visible neon orange (I have a neon yellow as well). Tight race fit; Me 6'1", 40" chest, lean, wear medium shirts. With Castelli I consistently wear large size for their jerseys, vest and jackets. This is my favorite jersey of all that I've owned, not just for climbing (Louis Garneau, Pearl Izumi, Giordana).
Own lots of Castelli but still occasionally get hung up by their fits&sizing - this is a skin tight fit so no forgiveness. Endomorphs only. Light but tight
I use it on the road and indoors. I like the lightweight for sweaty indoor sessions. It feels like they�ve made a slight change to the length. Reaching the rear pockets feels easier. I purchased the silver/black and it�s really sharp. I have always found Castelli to be very comfortable and durable. The fit is snug but not tight. 6ft 163lb and medium is perfect fit.
Feel safe and easy to see when riding ,fits well, good zipper
This was great in traffic, very safe and cool in hot weather
Never can go wrong with Castelli clothing. The light weight and breathability makes it perfect for the hot summers. Fit nice and snug but never to tight for my size 5�8� 150lbs size M
Another solid performer from Castelli. Especially living in the south in the summer
It's a great jersey, as I like a more fitted feel. Note however, I normally wear a medium (sometimes a L), but I am wearing an XL in this jersey.
