About Heat Holders Heat Holders are quite simply the warmest thermal socks and accessories you can buy! We started out in 2008 with a vision to create the ultimate thermal sock, warmer than anything else on the market. Since then, we've used our world-leading insulation knowledge to create ranges of thermal underwear, tights, hats, gloves, neck warmers and more. We also now offer a range of products to bring more warmth right into your home, including our toasty thermal blankets, which are available in a wide range of colours.

This makes our lighter TOG socks perfect for slipping into boots for walking. We also have our Original 2.3 which are perfect for those chilly nights at home as they are 7x warmer than regular cotton socks! * our TOG rating results are based on testing a sample cotton sock and a sample Heat Holders , according to British Standard 4745 two plate method for thermal tog rating.
