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.
