Men's Columbia Interchange Omni-shield Black coat sz M medium

One from my son's closet. 2 things: material on inside collar and sleeve trim kind of a soft felt-like material. While inside collar is in vguc the sleeve trim is rough on both sleeves (worse on the inside part as opposed to the outer). I personally would get some binding tape from Amazon and have a tailor sew on and would look like new. There is also one grey mark on the back just by the top (pic 7). I haven't aggressively tried to get out as concerned about ripping material so not sure if it can come out or not. Otherwise, it's a great coat.
