Just got this jacket in the mail this morning, LOVE it. I am guilty for being addicted to fleece jackets and I have a very large assortment, and I am very excited to put my first Patagonia jacket to good use. The only downside to this jacket is the lack of warm pockets, but this is a very small issue. For reference, I am 5'9" 195lbs, average build and the large fits great with room for a base layer. I probably could have gone to medium but I usually wear something under.
