A true three-season sock, the Signature Wool Sock pairs ultrafine merino wool with the same great fit and construction found on our summer-weight socks. Cuff height is 16-20cm (2cm per size) from the heel and features a 2cm double welt. A cross-hatch arch band and mesh construction across the top of the foot ensure excellent fit and high breathability, keeping your feet comfortable cross a range of temps. Merino wool is a naturally thermo-regulating and odor resistant. Nylon is incorporated for durability and longevity in high wear areas.
