HEATTECH ULTRA WARM black long-sleeved undershirt, made with heat-retaining material for comfortable wear. - Model Name: HEATTECH ULTRA WARM - Color: Black - Type: Long-sleeved undershirt - Size: 100cm~ Thank you for viewing. This is a set of two Uniqlo HEATTECH Ultra Warm shirts. I used them a few times for playing in the snow and school events. I don't think there are any serious stains, but there is some pilling from use. In addition, there may be other oversights, so I'm offering them at a low price.
