Italian made Vintage Wool Coat by Lineapi Size 44 green/rust blends 
It is wool and appears to be a polyester or silk lining. Only information given on tags are the size 44. 
With the wonderful slouchy boyfriend trends. The model is a size 2-4 and I think it's a very comfortable slouchy look and it's not too heavy either.
