chouyatouMen's Classic Notched Collar Double Breasted Wool Blend Pea Coat

Are these warm in winter?

How do you like the jacket ? How is the material ?

Say Prime shipping and can be delivered in 2 days, then in item description it says ships from China 7 to 14 days...... so which one is it?

I wear a size 43 sport jacket. What size do I need?
