Only the originals will do! Amazingly warm, with an unmatched 2.34 tog rating and magnificently soft, made from a specially blended bulk yarn, woven to provide extra long cushion loops that are then intensely brushed, Heat Holders are the ultimate in thermal socks. The intensively brushed inner isn’t only sensationally soft; it actually allows it to hold more warm air close to the skin, so you have warmer legs for longer! Oh yes, they now come in a great stripe pattern too!(03/11)Copied by many. Equalled by none.
