This is a UNIQLO Ultra Light Down inner vest. The size is M, with a chest width of approximately 45cm and a length of approximately 54cm. The color is a gray-brown glen check pattern. It has an adjuster and can be worn as a V-neck. It is an authentic product made with the highest quality down and feathers, and is quite warm even in mid-winter. It is USED, so there may be minor stains or damage, but it can still be worn and is recommended. Thank you.
