J.B. Field's Icelandic "30 Below XLR" Merino Wool Thermal Sock
The J.B. Fields "30 Below XLR" sock is ideal for those who spend a lot of time outside in cold weather and is perfect for winter sports. With a heavy weight, full cushion and soft merino wool they are sure to keep your feet warm and comfortable in the most extreme conditions.
The only difference between these socks and the "30 below Classic" is the "Double Cuff" (socks stay up better) and ankle/arch support (prevents slippage and bunching).
