I purchased these HOT WRAP warm underwear from Nishimatsuya. They are plain, in cream, beige to pink colors. I purchased them online for in-store pickup, but I couldn't wait and bought other underwear, so I'm selling these. They are new and unopened. I have the short-sleeved version of these, and although they are 100% cotton, they stretch well and have a moderate thickness that isn't too thin, so they seem warm. How about these for those looking for HOT WRAP long-sleeved underwear, 100% cotton, or Heattech? Sleeve Length: Long Sleeve Type: Innerwear
