Best winter jacket I've ever had
I want to keep it short, so will just say that I was wearing a long-sleeve and this jacket at -4F in winter and it was enough for me to stay warm. Note that I wasn't just standing somewhere on the street, but constantly walking. It's not too puffy, allows free movement, so I can truly say it's probably the best winter jacket I've ever had! I got the LT size (I'm roughly 222 lb, 6'1") and it fit perfectly.
Yes, I recommend this product.
