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.

Well made, looks good, etc. For $59, this is a good deal. Thank you guys for not liking army green!

SIZING is the big question when ordering this jacket. I've included pictures for you to see what a small looks like on me. 5'8" 150lbs, size 30/30 jeans. The waist is the smallest part of this coat and it wouldn't fit well if my waist was any bigger. I was drowning in the medium though at the store. It is more form fitting than most jackets, but I prefer that.

Some people want an oversized coat for layers...But if you get a coat that fits, you won't need so many layers.

The army green color in my photos is not accurate. The actual color matches the amazon picture very closely.

This coat will do fine in Wisconsin winters.
My two cents.

Great all round
