6'0 and weight has ranged from 180lb to 210 over the past decade. Fits me just right as an L (comparable to Arcteryx sizing). If I were closer to 180lb these days it might be a bit loose. Sleeves are a little long/wide compared to a comparable Arcteryx jacket.
I'm inclined to agree with other reviewers who have said that the cuff velcro is a bit overdone, stiff, aggressive, large, etc - On mine, the male-side cuff velcro is beginning to eat away at the sleeve fabric and pull material away - only major quality gripe thus far.
Overall, the jacket is workable as another shell in the wardrobe, especially layered with a fleece underneath in sub-freezing temps.
These are my go-to winter pants for EVERYTHING! Love the fit and durability.
