Heat Holders

(20 products)

The Heat Holders® process was, and still is, absolutely unique. It gives our socks the best thermal properties available, with a top rating of 2.34. That’s far warmer than heavy walking socks, nearly three times as warm as standard thermal socks and seven times warmer than basic cotton socks. 20 million pairs of Heat Holders® later, the message of warmth continues to spread all over the world.
