The average thermal sock has a tog rating of just 1.5, but with a proven thermal tog rating of 2.34, Heat holders can truly lay claim to being the Ultimate Thermal Socks.Heat Holders are made using heavy bulk yarn, extra long terry cushioning and an intense brushing process that combine to hold more heat in for longer.These striped Heat Holders have all the great qualities that have made them such a success, but with an eye-catching stripe – because being warm doesn’t have to be boring!Copied by many. Equalled by none.(10/11)
