This is Uniqlo's extra warm HEATTECH. I bought it quite a while ago, but I haven't worn it much and have kept it in my dresser. It has been washed with Oxiclean. It's still wearable. A long-sleeved T-shirt that provides a comfortable and warm feel thanks to HEATTECH technology. - Brand: UNIQLO - Model Name: HEATTECH ULTRA WARM - Size: M (Chest 88-96 cm)
