Muskin is a sustainable ‘mushroom-skin’ material, made from fungus spores grown in a woven pattern, extracted from the top of a mushroom. It’s processed naturally, without toxic chemicals, making it ideal for next-to-skin use, such as shoe insoles or watch straps. Muskin is hygienic, absorbing moisture and preventing bacteria growth. It has a soft suede or leather feel, is breathable and available in variable sizes.
