SealSkinz have become world-renowned for their waterproof socks and gloves. All their products feature a seamless three-layer construction - an inner layer to wick moisture away from the skin (Coolmax or Merino wool), an outer layer designed for extra durability and abrasion resistance, and laminated inbetween these layers is SealSkinz' patented 100% waterproof breathable membrane. This allows perspiration to escape whilst preventing water coming in. This membrane typically has 65% more breathability than other materials such as goretex. SealSkinz products can be used wherever you feel the need for waterproof, breathable protection. From fell running to window cleaning, from mountain biking to dog walking, SealSkinz provide maximum performance in wter, wind, rain or mud. This thin mid calf sock is the thinnest available from SealSkinz. It features a fine Merino wool inner for great comfort and excellent wicking performance and an elasticated instep for comfort and support.
