I've had this jacket for a while now and it has been wicked warm. I live and hunt in Maine, and we get real cold weather. When it comes to those long sits in the stand, this jacket shines. I sit in a 20ft stand and get hammered with cold gusts of wind sometimes. With this jacket I've never remotely felt like I was freezing, and I have the matching bib that goes along with it. Get the set and it will be the warmest hunt in the coldest of months.
