Hotcott 90 size, a set of 4 long-sleeved shirts in black and gray. - Brand: Hotcott - Size: 90 - Colors: Black, Gray - Item Type: Long-sleeved T-shirts - Quantity: Set of 4 Thank you for viewing. My child didn't wear these much, as they seem to get hot easily. The gray ones are a bit thicker. Made of 95% cotton, they don't feel cold and I personally find them warmer than Heattech. They are also gentle on the skin. They look quite faded in the images, but in reality, they are hardly faded at all. There is a name written on the inside, which has been marked out. They're too good to waste, so please take them if you'd like them ☺︎ Uniqlo Heattech gu Nishimatsuya Warm
