To make CLIFF belts, layers of cork are laminated to fabric, creating a durable, lightweight and supple material. Each belt is handmade and individually crafted. Cork is environmentally preferable to leather as it comes from a lower carbon impact source (tree bark) and does not use animal products in its manufacture (a vegan product). The environmental concerns associated with leather include the energy and carbon intensity of generating animal products and the chemicals used in the leather tanning process that can be damaging to human health and the environment. Cork is a naturally beautiful and greener alternative to leather.
