I got a great deal on a pair of the pros, but I went a bit larger in size like I do with most brands of bibs. Unfortunately, these measure waist more like american clothing companies do than european, so I really could have gotten away with larges (or maybe mediums), but by then the deal was gone, so I kept them rather than returning them to pay for half a pair of larges. The jersey I bought at the same time fit european (super tight in the chest), but I was surprised at how big the bibs were. Nice pad, just bigger than expected (and I'd specifically bought them because I've lost weight and my old bibs aren't fitting as tightly as they used to).
