This coat is thin but warm. The material has a great feel to it. I am 510 and it is long and sleeves r perfect length. I debated about size after reading reviews but ordered a large and glad I did. It fits perfect.
(Some of the coats I already have are size large and some medium, but large in this coat is great).
I am very happy with this purchase. The only thing I wish was different was a flap to cover zipper. But I love coat anyway.
