Heat Holders Neck Warmers black

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 reconfigured.
• Our strictly guarded "unique brushing process" maximizes the amount of air pockets that trap warm air inside the sock.
