Until purchase of these bibs, I'd only ventured into the PI PRO line of apparel. I must say, these bibs leave anything I've tried thus far in laying in the corner of my closet (literally). I have three issues with these:1. I wish the inseam were a bit longer (Im 6 and ordered a L). After some riding, they end up being little less than half-way up my thigh (closer to the knee).2. The straps tend to hug the goods a little too much. Very uncomfortable on long rides.3. They are not quite "black". I have a "black" castelli jersey and they DO NOT match. These bibs are more of a blue-ish-black. Aside from the aforementioned, Id say they are about perfect. These bibs resolved a lot of saddle sore/chaffing issues I had experienced in the past.
On a side note, I got an XL in the Aero race bib (same pad) and I like them much better. Probably due to the fact that my tackle is not smashed against my body with the XL. I'll try the XL body paint next. Seems to me that the fit (geometry and stiching) is exactly the same between the two.
