A pack of three pairs of undyed organic cotton ankle socks with a soft brushed sole. Each pair naturally fits into your wardrobe regardless of season and occasion. Knitted with naturally colored cotton (Chamen), the brown pairs are undyed, let alone the ecru one. The gray color is created also not by dyeing but by causing a chemical reaction on rare pale green cotton (Midorimen), while applying a plant dying method called mordanting to fix the color. The color was born as a by-product of a study to prevent Midorimen cotton from color fading by sunlight because the material inherently has low color fastness to light.
