The materials have been carefully selected to enhance heat retention. - Brand: Danro (Fireplace) - Size: L - Suitable Sizes: → Height: 170-180 cm → Chest: 78-88 cm I purchased this new, but I'm selling it because the top felt tight when I tried it on and I don't want to wear it. The pants that I'm selling have never been tried on and are brand new. I threw away the outer packaging. It's stretchy and designed to fit snugly. This item fits snugly, so it's for someone who doesn't mind a close fit. It feels very warm. There is one stain from storage. I think it will come out if you have it cleaned. Considering the above points, if anyone doesn't mind these issues and would like to use it, please feel free to purchase. I would appreciate it if you would consider purchasing. Thank you.
