GU Style Heat Size: 120 White and navy blue striped pattern. Thicker and softer to the touch than Heattech. Although the size is 120, it's a bit large, and I think it's equivalent to a size 130. There is some pilling, but no scratches or stains. I also have long-sleeved underwear for sale ☺︎ If you would like to buy multiple items, please comment ☺︎
