The J.B. Field's "30 Below Classic" is the best-selling winter sock in Canada!
Made from 70% merino wool and featuring a heavy weight cushioning throughout, these socks will keep your feet warm from zero to -30°C. The high content of merino wool also helps wick moisture and keep your feet dry and blister free when doing outdoor activities in cold temperatures.
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.
Also available in a knee-high version
Also available as a 1st Quality 30 Below Crew Large Denim 3 pack
Please Note: the mediums come with a line across the toe and 'Icelandic' written on the sole of the foot.
