I bought it for the exact reasons stated in the description. I live in Arizona and wanted a lite, cool jersey for climbing and just riding in hot weather ( I really don't like climbing). I needed to go up THREE sizes, from a medium to a 2xl. It has very small amount of slack in the chest and waist. (5'11 180lbs., 41 chest, 37 waist and a weight lifter). Those are actual measurements, not the size of cloths I buy. I was shocked by my true waist size since all my purchases are a 32 waist. I wear a medium bike short in PI. I think manufactures are trying to make us feel good about ourselves. Just purchased a Castelli Free Speed Race Jersey in XL. It looks pretty much like it's painted on, but I think I will keep it. Motivation for shedding 5 more pounds.
