Uniqlo Heattech Ultra Warm, black long sleeve, size M. I've used it a lot, so it's stretched and thinned in places. It shows signs of wear. I think it can still be used as an inner layer. It's definitely warm. Please check the condition in the photos and understand that this is a used item. #Uniqlo #UNIQLO #Heattech #UltraWarm #Women's #M #Black #UltraWarm
