Frequently Asked Questions
Everything you need to know about the world's warmest socks and thermal apparel.
What makes Heat Holders different from regular thermal socks?
Heat Holders use a unique three-stage process involving advanced thermal yarn, a patented long-loop cushion pile, and an intense brushing process to trap maximum warm air close to the skin.
How should I wash my Heat Holders products?
To maintain the thermal efficiency and softness, we recommend machine washing at 40°C (104°F) and avoiding tumble drying. Always wash dark colors separately.
