I really love this coat!! I live near Niagara falls. So it's cold af. The windshield gets to -40 sometimes. It is good by itself as low as 20 anything less than that needs a good jacket underneath. That being said this coat is tough! I'm usually a size 8/10 but I bought a 14 in order to layer it. The only disappointing thing is that the pocket has begun to unravel at the seams. But a quick going sewing will fix it up!
