I had no idea that this sweatshirt was lined (throughout the body and hood) with soft furry material. the lining is a lighter shade of grey (I bought the black one)and very warm. The sleves are also lined just with cotton fabric, but still very nice. The main interior stitching is trimed with purple fabric, (I think this is to make the stitching more durable) so along the seam that connects the hoo with the body is purplr and along the seams that parallel the zipper is purple. the purple makes for a nice subtle accent. A size medium is usually roomy for me but this one fits just right, so the size runs ever so slightly smaller than I am use to. I honestly couldn't be more happy with this item, infact I am thinking about getting another one of a different color.
