Philip H.wrote a review of Castelli Superleggera Jacket - Men's on January 11, 2018
Familiarity: I've used it once or twice and have initial impressions
The Large is a perfect fit for me, snug but not stretched. I'm a 38 chest and 32 waist. It does have a stretch panel in the back so will accommodate a slightly larger sized person. Its light and is easily stuffed into a pocket to carry when it might rain. It also acts as a good wind break and for early morning starts before it warms up.
