I ride in both the Elite and P.R.O. stuff. The PRO material is a little lighter and cut a bit tighter than the Elite level stuff. I like both, but for my height the Elite bibs have better fitting straps than the PRO bibs. I think the Pro is a bit cooler on warm days, but not a lot. I don't wear their jerseys. I also have some PRO bib tights I got on sale for nothing. They are nice and thick and warm, but there have been only two days all winter on which I felt the need to wear them. All other days have been PI Elite knickers and a jacket.
