i'm 6'2 185 and i wear an xl cosmic. it fits me totally normally. very little extra bagginess and i by no means dress like a jibber, i use it as a backcountry shell. given your size i think you can squeeze into the xl since there's enough width for it to accommodate a heavier guy, but if you want something more jibber style then get the 2xl, but the xl will be great as a standard alpinist cut shell. plus theyre longer now than last year
