Stay warm, stay dry with mens and ladies Heat Holders Waterproof 2.8 Tog Socks. Made with all the benefits of Heat Holders’ famous thermal insulation, now combined with technology that adds waterproofing and breathability for complete protection against the elements. These soft, comfortable socks also notably lack the hardness and harshness that normally accompanies waterproof socks. These dense, thickly knitted outdoor socks use the advanced Japanese designed thermal yarn that gives regular Heat Holders their performance insulation, superior moisture breathing abilities and softness. Added to that, innovative knitting technology produces a long, looped cushion pile that then goes through an expert brushing process that maximises the amount of warm air held inside each sock, giving them their TOG-rated unbeatable warmth and all-day comfort.
