Thank you for viewing. This is a black diamond fleece, aluminum-lined jacket purchased from Workman. According to the tag description: The back lining has aluminum print that emits far-infrared rays, and the outer material is a fluffy, warm diamond fleece fabric, providing high heat retention. It performs excellently as an outer for everyday use or as a mid-layer inner on cold days. - Brand: FieldCore - Size: M - Color: Diamond Black I bought this, a different color from the one Kimutaku wore on TV, which was a hot topic, but the size didn't fit, so I'm selling it with the tags still attached. Please understand that it has been stored at home (no pets, no smokers). Also, I am selling it elsewhere, so there is a possibility of sudden removal from sale. Thank you for your understanding. #Kimutaku #Workman #FieldCore #DiamondFleeceAluminumLinedJacket
