I have a pair of these and a pair of the elites also. The pro's are made from better material, and I think the elites are a little larger in the same size. I alternate riding them every day with some other bibs, and I don't find much difference between the two. The pro's fit tighter, more support I guess, and they stay drier than the elites. When I buy my next pair, it will probably be based on price. If I can get a great deal on the pros, I will get them. And I would be willing to pay a little more for them.
