The J.B. Field's "30 Below XLR" thermal sock is ideal for those who spend a lot of time outside in cold weather and is perfect for winter sports. With a full, heavyweight cushion and soft Merino wool, they will keep your feet warm and comfortable in the most extreme conditions.

Merino wool is a type of wool that comes from a merino sheep. It is the finest wool on the market, making the fabric soft and itch-free. It is also breathable and temperature-regulating, so your feet are not too hot or cold. Merino is one of the best fibres for wicking moisture as it can absorb up to 30% of its weight in moisture and moves it from your skin to the outside of the fabric, where it evaporates. Because it stays dry, odour-causing bacteria cannot grow, making it a naturally antimicrobial fibre.
  • Merino Wool Socks: 70% Merino Wool, 25% Nylon, 5% Spandex
