One of the best jackets ive had the pleasure of owning and wearing. A lot of people talk about the cost of Filson jackets, but they are worth every penny. This jacket is durable, looks great, and keeps the wind and cold out. Im 6'2 and my weight fluctuates between 200-220 ( I tend to drink a little more beer in the winter time ha), it fits through all seasons. I obviously dont wear it so much in the summer, but you can with a t shirt. I like to wear a long sleeve or sweatshirt underneath it. Has a lot of pockets and such, fits right at my waist, and looks great zipped up. It does run a tad bit large, but i think its more of the cut of the jacket though. You need to figure out how you like to wear Filson jackets. Sure, i could wear the medium, but i like the fit of the large. If you usually wear a XL, order a XL and L and try them both on. Return the one that doesnt fit. This will save you the headache of waiting for the right size to come.
