I have been wearing Cento bibs exclusively for several years now. The cento bibs have the most padding, 10 mm rather than 8, of any Assos model which I prefer. Also the straps on the Cento model are particularly wide and comfortable. The evo are a noticeable improvement over the s7. The front kudu pocket is a lycra type material rather than fabric, the padding is black and the straps even better than the s7, which themselves were excellent wide and comfortable. Note that the sizing is based on height and not weight or waist size. The bibs fit better if not bought larger than recommended, the padding will seat, position better. I'm 5'7 and medium is the recommend size for me and fits me better than large (which I also own). Although the s7 are still being sold and are a bit cheaper, I feel the evo are worth the additional cost. When Assos makes improvements, the improvements address technical issues and are not simply cosmetic marketing.
I am almost 62 and weigh right at 150 pounds. I like the way the medium fits me (not a lot of loose material in body or arms). I use it when I have been out and find that I need a jacket. It fits neatly inside of my jerseys back pocket.
I have several pair of these, both new and some still around not so new. I think the strong point for these is the fit. I think the chamois is good, but not as good as some Italian designed shorts (but whose fit is too small.). These are my favorite by default and great value when on sale.
