This is a set of knit underwear, top and bottom, designed to keep you warm. It's FUKUSUKE underwear. This underwear is excellent for warmth in the coming season. The materials have been carefully selected to enhance heat retention. - Brand: Danro (Fireplace) - Size: L - Suitable sizes: → Chest: 90-98 cm → Height: 170-180 cm → Waist: 78-88 cm I purchased this new, but I tried on the top and found it too tight, so I washed it at home. I have thrown away the outer packaging. The shoulder area is double-layered and has a brushed back. It's stretchy and designed to be worn snugly. I think it will be very warm for those who don't mind a snug fit. Considering the above, if anyone is not concerned about these points and would like to use it, please feel free to do so. Thank you for considering purchasing this item.
