It took 3 pair to get the right fit, but I finally got a pair that does. I'm 5'10' 180 lbs. and had to get the xxl. I've worn them with temps in the upper 20's F. I ride in colder weather also, and have to wear something more for that. Overall a good fit.
These are the best bib tights that I've ever had. Very comfortable in a wide range of temperatures. Very pleased with this purchase. Like them better than my Assos. Don't believe I've said that about anything else before!
