I have zero experience with Campy clothing. The only thing I can say from experience with other manufacturers, is never buy winter cycling clothing from a company that's headquartered in a warm(er) climate. I've got a few sets of "winter" cycling gloves and tights from Pearl, Cannondale, etc. that aren't worth the fabric they were made with. Now louis garneau and sugio stuff, that's good winter stuff.
That being said, IMO, campy does a pretty good job at everything they do.
