Very warm and very well designed, when the hoodie is done up is pratically a parka setup, only problem I had js since its a flight jacket go a size up then what you would normally get so if you fit large probs best to get a xl size. Since I am tall bombers typically are a odd fit in this case it fits well just when the hoodie is done up it feels stiff and it stops me from turning my head as far as I would like but I think thats its design aswell when you do have it up like that, keeps me very warm in -20 to -30s with only one hoodie underneath, you got a cotten shirt with a crew neck under you are set for the cold imo
