Uniqlo HEATTECH set, long sleeve and short sleeve. I bought these to wear under shirts for business trips, but I haven't had the opportunity to wear them, so I'm selling them. I think I wore the short sleeve once or twice, but I don't remember wearing the long sleeve at all. The condition is very clean. - Color: Beige - Model name: HEATTECH - Size: M Please note that I am not accepting price negotiations. Thank you for your consideration.
