This is a very nice vest. I got burgundy. It is warm and has a packable bag.  I am 34"x24"x34", I ordered the medium.  The bust area is fitted, the waist and hips are a few inches too large.  If you have the same measurements but have a smaller bust, get the small, it will fit perfectly.

The collar is huge, like a cowel neck when zipped all the way up. It covers my butt area completely, I am 5'6".  It is just as shown.
