Environmental protection material: Merino wool is natural material because it is from Australian sheep. In the final use of the life cycle, Merino wool will be biodegraded into soil to provide nutrition for trees and plants.

I guarantee your feet will feel warm and dry in the cold winter, Merino wool socks.

Australian Merino wool: Men's mountaineering socks are made of 53% organic Merino wool, 25% nylon, 17% polyester and 5% spandex blended materials, which are durable and elastic. Merino wool materials are imported from Australia and New Zealand, where Merino sheep are raised. We use their natural wool to make clothes without harming Merino sheep. The wool comes back every six weeks.
