HEATTECH EXTRA WARM material, size 160 kids' spats, set of 2 colors: gray and black. - Color: Gray - Color: Black - Size: 160 - Material: HEATTECH EXTRA WARM Thank you for viewing. The inside is boa (fleece-lined), which looks very warm. I had planned to wear them and both were home-cleaned, but they didn't fit my child, so they were only tried on (only the black one was tried on). Please understand that these items have been home-cleaned and tried on. I will clean them with adhesive tape before packing, but due to the nature of the color, the black one may show some clinging particles. Please understand. No individual sales.
