Boys Columbia Ski Coat M

This is the boys "Arctic blast II insulated ski jacket" in a size Medium (10-12). Bought last season as my son wanted a warm coat, however he hated the built-in snow skirt and said it was too puffy. It has probably been worn about ten times in total, he just wouldn't wear it. There is a small fit on the zip (see photos) where a 'tooth' on the zip is missing, I hadn't even noticed and I think it may be an original fault I hadn't spotted. It doesn't affect the quality of the coat and the zip works fine. I have washed the coat (per washing instructions) and it has left a slight water mark on the left shoulder as worn (see photo) but it will probably come out if washed again. Currently £90 from Columbia. Can send immediately in case needed for a half term ski trip.
