They definitely feel tight; I guess they marketing spiel would call it "compression"?! I'm 62kg or thereabouts and 6'2, maybe a medium would have been baggy on my thighs which is what I always found with Rapha, even in a small TBH. Sigma had them on offer at £100, and you can get a tenner off so @£90 I reckon they're decent. The straps have lots of give so they don't crunch your shoulders down. Quite hard to take a piss in though. Hope that helps!
