Uniqlo Heattech, 140cm. The color is light green (a color that looks like light gray or light blue). It's a long-sleeved type, but the sleeves are nine-tenths length, so they won't easily peek out, which I think is convenient. Although it's new and unopened, it has been in someone's possession once. Please refrain from purchasing if you are sensitive to this. No smokers or pets. Will be shipped via anonymous delivery.
