These double face socks have been in ROTOTO’s collection since the establishment of the brand. Designed with an inspiration from mountaineering socks, the item features merino wool on the surface and undyed low-count organic cotton fabric as the lining to create a soft and thick feel like a sweatshirt. The liner material feels fluffy and comfortable with a napped surface.
