I usually steer clear of bib tights because they are generally too short in the legs for me, but these fit great. Plenty long enough, snug in the body, a nice amount of compression in the legs, and a very comfortable chamois. They're plenty warm, too -- I've worn them when the temperature was in the mid-30s and they keep me nice and warm. Plus, they don't overheat when the temperature starts to climb. Nice wide shoulder straps make for a comfortable, non-chafing fit, and reflective trim helps with visibility in low-light situations. I haven't had them out in a heavy rain yet, so I can't speak to their water resistance.
They are made with the thoughtful design and quality materials I've come to expect from Assos. They weren't cheap, but they are very high quality. Much more comfortable than other brands I've used.
My only suggestion: add a zipper at the ankles. The snug fit that keeps the heat in and the cold out makes it a little tricky to get into and out of these tights. A zipper would make putting them on and taking them off much easier.
For reference, I am 6'2", 185 lbs, and typically wear pants with a 34" waist and 36" inseam. The large fits perfectly.
Finally, Assos has come out with a bib short for a tall, thin guy, like me. I had gotten the impression that Swiss riders must all be short stocky guys with large quads, based on previous Assos bibs I've tried. I was anxious to try these as soon as I saw they were being offered in a long length, but I've been disappointed with expensive shorts before, so I did not want to lay out the $xxx list price for these. Even though the WesternBike sale price I got them for was still up there ($xxx.xx), if they hold up, it will have been worth it. These shorts certainly have the thickest pad I have had on any shorts, but I guess the designers did substantial testing before incoporating it in these bibs. I have had no issues with chafing, and find the extra padding very comfortable. I am 6'2" 170lbs, 34" waist. Either a large or med fits, but I prefer the compression of the medium, and previous Assos large have gotten looser with use, especially around the leg opening. The straps are a little tighter in the medium when I stand up, but not terribly so, and not noticeable in riding position.
I'm tall and thin. Great sale price for these, and I've wanted to try a pair for a while. But for a tall thin guy, like me, I have found that these, like other Assos bibs I have had, are cut too short. I returned these after trying on, but I also ordered a pair of the Mille GT summer bibs in a long, which I had never seen offered by Assos before. They fit great, so I exchanged the RS S9 for a second pair of the Mille GT's also on reduced price. I am 6'2" 170lbs, 34" waist. Either a large or med fits, but I prefer the compression of the medium, and previous Assos large have gotten looser with use, especially around the leg opening.
In hot weather (over 80F), my head sweats profusely, overwhelming all caps and other sweatbands. Not this. Itï¿½s lightweight, soft and super-absorbent. I bought a second one for training mid-week then bought the beanie version for days in the mid-90s.
