Funny, I always wear a size S (55.5/56cm) in helmets and found the Nexx to be slightly generous. It is definitely more roomy than say, a Schuberth C4 Pro (which is nice and tight all around) and also roomier than the Eliminator in the top, rear & crown of the head.
But I guess we all have different shaped heads and no fit can ever be perfect.
