This is an outerwear purchased at Costco two years ago. It has a thick, substantial, and slightly stretchy feel, with mesh around the chest area. The rest of the lining is brushed, and the surface also seems to be water-repellent. I wore it once, but it seems it wasn't to my liking, and it has been stored at home since then. I'm selling it since I don't think I'll wear it in the future. Please consider that this is a used item that my child wore once. Outer: Polyester 97% Polyurethane 3% Lining: Polyester 100% Size: 10/12, equivalent to 150-160cm
