These new R1001 DOUBLE FACE SOCKS are knitted with naturally colored organic cotton (Chamen). Maintaining the original shape and comfort, this model comes in low-key color options. The fabric feels like a soft sweatshirt, while the design is inspired by chunky mountaineering socks. The item features merino wool on the surface and undyed organic cotton fabric as the lining with a napped surface for a soft and fluffy feel. With these socks, you can enjoy a comfortable touch of organic cotton fabric to the fullest.
