Butt and saddle matchmakers
If you ride a lot, you know how important bibs are, and more important is the quality of the chamois. For me, these bibs are the best I've ridden overall. The quality is good in every aspect, including material, the bib itself, and the chamois. They are a bit expensive compared to others, but for me worth it.
On all-important sizing, I'm 5'10" and 156 lbs. and the large fit me just right. The thighs fit very tight, which is due to the compression fit of the fabric. I also have the Castelli Velocissimo bibs which are more mid-range and those do not have compression, in case that matters to you.
The second ride I did in my Free Aero bibs was in the 110 mile NY GranFondo and they were really great; comfortable, and best part is I didnt think about them at all. I also like the restraint in not using too many colors and designs, as I'm a fan of the more classic black shorts with just the right amount of logo placement.
You can read about all the additional features in the RC description, but I rate these very high.
