I am 5'10, 195 lbs, I purchased this shell in size large. The fit is very roomy layered with clothes to be in a 10 degree temperature environment. It has plenty of pockets and inside storage. There is plenty of room for my helmet under the hood. The snow / draft shirt works well. The jacket's fabric is soft. The only thing it's missing is hand sleeves. I rate this shell jacket a 9.5 out of 10.
