These really are good value bibs. I prefer the chamois to their standard Ultimate pad. I wish they would start offering this chamois in their other bibs (summer, cargo, winter)--it's a lot better. Whereas I got a bit of numbness after 20 miles or so in their Summer Ultimate bibs, I don't in these.
As far as the fit goes, I'm 6'1" @ 185 lbs with a 32" inseam. I'm between sizes for The Black Bibs. I prefer the compression I get from L but the straps on that size feel a bit too short. The straps are more comfortable on the XL but they're not as compressive. Still totally usable either way; just a matter of what you prioritize.
My main gripes with these bibs--and what ultimately convinced me to pony up for bibs in the >$200 price range elsewhere--is the cut of the chamois that makes it hard for me to go much more than 30 miles in these things.
(1) Purely aesthetic: I get major MAMIL toe in the front and I'm a bit self conscious when I'm off the bike.
(2) More functional: the pad is cut either too high or too low in the front depending on how you look at it. The end of the chamois and the seam where it joins up with the lycra is directly over my bits and pieces when I'm in the riding position. This leads to some really annoying rubbing that has me frequently adjusting myself while riding and can get painful after a while. Makes me want to stick a sock in there or something.
If you're built different down there and don't have the same issues I do with the chamois then these undoubtedly become some of the best non-cargo bibs you can buy for less than $200. As it is, these are my go-to bibs for shorter rides but I reach for something else when I'm going to be spending more than an hour or so in the saddle.
