Simms sizing can be all over the map depending upon the product. I am 5'7" and 160lbs and the medium fits a bit loose, but comfortably so. The medium cold weather shirt was huge, but the small is perfectly sized. This being said, another high quality Simms product.
Great everyday work wear but nice enough for client meetings
I love this thing! It holds the heat in well enough that most fall days on water, I wear a compression shirt underneath this vest and call it good. Add a jacket over top when it gets cold and I haven't been cold in Montana yet!
I have the black vest with Windstopper and pocket drawstring waist, and expected the same, except for color. I do not like the way this one fits at the waist. I'm now also hearing from friends that quality of vests is not as good as in previous years.
