These 36x34 jeans are for the guys who think that many 36x34 cuts are *slightly too tight.*  On the universal scale of mens jeans, these are a fairly loose-fitting 36x34.  Id recommend these for a guy 64 - 67 (190-200cm) and 225-240lbs (102-109kg)

Im 66 and 235lbs, for comparison.  Id say 2/3 of all jeans at a 36x34 cut are slightly too snug in one way or another, but 38x34 is usually too loose. This pair hits the perfect medium for me, resulting in a comfortable fit that stays pretty uniformly loose-fitting through the hip and leg.
