Great warmth

I am on the border of large and x-large with most my clothes (36" give or take waist). From other reviews, I read it's a little big, so decided to size down and went for the large. It fits nice with a t-shirt underneath, but not a lot of extra room for my... ugh... expanded mid section. With a fleece mid-layer, it's a bit snug me. So if you're right on that L/XL line in most your clothing due to an over-indulgence in yummy trail treats and plan to wear over thicker clothing, I'd go with the XL. But if you plan to be using it as a summer raincoat over just a tee for hiking and so on (that's my plan with it), then I'd go with the L. It's really that fine of a line for me.

This is a very lightweight rain jacket, basically. I like that it is very waterproof and the hood comes far enough forward to shield your face, and has an inner hood type thing you can tighten so even in wind it wont blow the hood off.

There's a soft layer of mesh for the lining, which feels nice, but don't expect it to keep you warm by itself--very good for a spring jacket, but in winter definitely need to layer.

About the fit: it's hard for me to fit jackets sometimes. I'm 6'1" but 175 pounds and don't like my clothing to fit too baggy, so I went with the medium. It's length is fine--like in the picture. The bottom has an adjustable elastic thing too so you can bring it in if need be. I like the gray color. I would buy again.
