This is a Columbia vest, and it's one of the best. It's a thin vest, perfect for the coming season and into early autumn. The size is US S, but it's a bit large. I usually wear a Japanese L size. The width is 51 cm, and the length is 68 cm, but the sides are made of stretch material, so there's quite a bit of give. The color is black, and it features Omni-Heat with a heat-reflective lining. The original price was around 10,000 yen. I wore it for about a month last winter. I also wore an outer jacket over it, and I mainly used it indoors, so there's no noticeable dirt. I've prepared something different this year and won't be wearing this, so I'm putting it up for sale. Please understand that this is a used item, and I appreciate purchases from those who are not overly concerned about minor imperfections.
