I purchased this a few years ago at either Birthday or Nishimatsuya. I used to put these on as an inner layer during the cold season, but I only wore them once or twice the year I bought them, and then stored them at home. I cut off the name tag from the green inner layer because I had written my name on it. This is a set of two. These are long-sleeved T-shirts made of thick quilted fabric, so I think they will be warm. - Material: Quilted fabric - Color: White - Sleeve Length: Long sleeve Thank you for looking.
