Armour Cloth - a very stiff but robust waxed cotton fabric
Once invented to protect the cargo of cars and trucks at the beginning of the 20th century, it was only a matter of time until armor cloth was also used for outdoor garments. It's robust, water-repellent, and offers great longevity. But be aware that this fabric needs to be broken in! Once tamed, the material provides great comfort and rewards the owner with a great patina over time.
