I normally wear a 36x32. I originally bought a 36x32 and they were super tight....too tight. All the reviews said to buy bigger. Should have read the reviews...I got a 40x32 and they are a good fit. A little loose, but I am betting after I wash them they will shrink a little. I have a little room that I could wear thermal underwear too and still be comfortable.
So far they seem good. have yet to put them through the test and actually wear them while riding.
