The J.B. Field's "30 Below Classic" is Canada's best-selling thermal sock! 

These socks are made from 70% merino wool and have 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
