This coat is INCREDIBLY warm. I bought it for skiing in sun-zero F days in New England and it has not let me down. If your are going to do any physical activity in this, you won't be able to wear it if it is just "cold" out. I tried skiing with it in 10F and only a long sleeve base layer. I was sweating. But -15F with 30 mph winds? Cozy!!Skiing through the tree with this, it has gotten snagged on a few branches without issue. Any lesser fabric would have definitely yielded and torn. The Cordura is bomber.For a coat it's size/warmth, it is super light! But it is bulky so don't think you are going to be able to stuff this sucker away. It's like walking around with a sleeping bag if you're not wearing it. You need to be a little careful about planning your movements as you are about 6" wider than you would normally be!
