I use the jersey for my summer commuting and training, usually one in the same. I prefer the longer sleeves the jersey has and the fabric is soft and evaporates sweat very effectively. I wasn't too sure about the tail of the jersey when I first got it, but it seems to do a good job of staying put and provides a little easier reach into the back pockets. Liked it so much I bought another.
I always turn to my Castelli jerseys when I know it's going to be a hot day but am always apprehensive about purchasing them because of the size challenges. I'm consistently a men's L in every other brand, but my Castelli jerseys are all either XL or 2XL depending on the line's cut. I'm 6'1 and currently 188 (not an athletic build) and have this jersey in a 2XL that fits very comfortably for day-long rides...appropriately snug and fitted without being compression-tight, with no extra fabric flapping in the wind.
