I did a lot of research on winter parkas. I live in Boston where the winters can be brutal and I am moving to Russia for a couple years and needed a VERY warm coat for everyday. My first thought was to get a Canada Goose parka. I know people who have them and say they are great,but ... problem is they are not very stylish,and too many peoples have same patch... I wanted a very warm Canada made coat that would also make somewhat of a fashion statement. This parka definitely does both. The fabric made in USA and huge coyote fur on this coat is far more luxurious than the Canada Goose parkas. The extra origin real beaver fur chin guard is a super nice feature that was not available on any other parka I have found\just Tom Ford\ IIt is awesome on every level.For reference-I ordered this parka in Size M which is perfect. I am 5'9- 143 pounds., size 8 clothing Normal arm and leg length.There is not a ton of room to spare but with the weight of this coat I would NEVER want to wear a big thick sweater. It would be smoldering.I mostly wear cotton long sleeve t shirts or maybe a fleece half zip. I wore this with a t shirt and it was 12 degrees outside. I was plenty warm without the added bulk of a sweater which was great! Thank you for warm coat.
