I bought this for my husband, but I ordered the wrong size, so I'm selling it. Brand new, unused. It seems warm with a fleece lining. Set of 2. I can also offer 2 sets (4 pieces) for 1800 yen. If you'd like this, please leave a comment. *I will take it out of the outer bag, fold it, and compress it for shipping. -------------------------------------------------- # Fiber Heat Heattech Undershirt Men's Innerwear Underwear Lingerie
