Very good product
I got the top and bottom for my base layer for hunting. On the way out to my stand it was about 25 degrees. These things are so warm I had to unbutton my jacket. Once I was in my stand they kept me very warm. If you do anything in extreme cold conditions then you will want these. Great product.

Warm but not Extreme
It’s warm but not Extreme “Super-cold” warm. Honestly doesn’t seem any different than any other base layer I own. When the wind blows I’m still froze.
