This is very similar to the Maison jersey by Castelli. The fabric is very lightweight, soft and stretchy. I wore it in mid 80 degree temps, and was very comfortable. The zipper is good. The rear pockets are roomy and stretchy. The sleeve length is longer, but not too long. It feels great on. I'm 5'9", 160lbs, and got a Large. Very happy with this jersey.
Summer in Texas is HOT and the Castelli Rapido Jersey is as cool a jersey as I have found for riding in the Texas summer. The fit is great too. Five stars!
typical euro sizing,thin material good for heat, unsure of grey color
Good summer cycling gear,
