PLEASE NOTE: The product comes with a Christmas card so you can give the product as a gift to your friends or family at Christmas. FLEECE-LINED: Women's thermal bed socks have a super soft brushed fleece lining, making them incredibly warm and comfortable; brushed fleece inner lining is incredibly soft to keep your feet cosy in cold weather. THERMAL: The soft brushed fleece lining works by trapping your body heat to provide optimum insulation and keep your feet warm in winter; thick, high-quality fabric is temperature regulating to maintain the ideal level of warmth. COMFORTABLE: Added-stretch fabric and super soft fabric provides a snug, streamlined fit for comfort while allowing for complete freedom of movement; turn over top ensures these women's thermal socks don't slip down. ANTI-ODOUR: Made from lightweight, breathable fabric that prevents the build up of sweat on the feet; immediately wicks away moisture from the skin and attacks odour-causing bacteria to keep your feet feeling fresh. DURABLE: Unlike some lower quality bed socks, we use advanced weaving technology and high-qualiy fabric to prevent socks from shedding; machine-washable to they maintain their premium finish and fit for longer. Material: nylon. One size, suitable for 37-40 yards.
