The J.B. Field's *30 Below Classic* is Canada's best-selling thermal sock, designed to keep your feet warm in temperatures as low as -30°C.
Made from 70% merino wool, these socks offer exceptional softness, moisture-wicking properties, and temperature regulation. The merino wool absorbs moisture, keeps feet dry, and prevents odor, while its natural crimp traps heat for added warmth.
Featuring heavy-weight cushioning throughout, these socks provide extra comfort and protection for outdoor activities in cold conditions.
Available in various sizes, including knee-high and slightly imperfect versions.
Note: Socks fit large, so consider sizing down if possible. Due to the thickness of these socks we recommend having enough room in your boots
