Heat Holders Children's socks 34-39, pink

How they work
It is only through the absolutely unique three-stage knitting process that Heat Holders achieve their outstanding heat-retaining properties.
The acrylic yarn used for Heat Holders feels like cashmere and is a highly sought-after yet difficult-to-source product, with limited production capacities worldwide. This superior yarn gives Heat Holders their unmatched soft and comfortable cashmere feel.
Many technological innovations were required for the famous long-looped thermal fleece in our socks, and our machines had to be completely retooled.
Our strictly secret unique brushing process maximizes the amount of air pockets that trap warm air inside the sock.
