Uniqlo's extra warm black men's M size, set of 2. I'm decluttering, so I'm selling these. ☆I have many other items for sale. Please take a look if you'd like♪☆ → #Yasu-kun This is the most balanced product among Heattech and GU's Style Heat series. In my personal opinion, it's warmer than innerwear from Workman, Muji, Gunze, etc., and it's durable and doesn't wear out even after washing. Please understand that these are used items before purchasing.
