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 are sure to keep your feet warm and comfortable in the most extreme conditions.

The only differences between these socks and the "30 Below Classic" are the double cuff to help socks stay up better and both ankle and arch support, which prevents slippage and bunching.

Soft, warm, and durable: Merino wool is a versatile fibre that wicks away moisture and keeps your feet dry, blister-free, and smelling great. Due to a lower micron width per strand, it is a finer type of wool without the itch.
