I love this Jacket. Only real complaint I have about this jacket is that I tore it the first time I wore it. I should have been more careful. I think a roofing tac actually was the culprit. My dog jumps up on me all the time. He weighs around 100 lbs. His nails don't do any damage to my jacket though. But all in all, it's the warmest and lightest jacket I have. I used it in 20 degree fahrenheit while camping and it was about as expected. I was warm under the jacket but in that kind of cold it was hard to keep the rest of me warm.
