The archetypal tote is made of sturdy cloth, perhaps with thick leather at its handles or bottom; leather versions often have a pebbled surface. Common fabrics include heavy canvas, possibly dyed, or treated to resist moisture and mold. Jute is another traditional material, though less popular. In recent decades, heavy nylon and other easy-care synthetics have become common, although these may degrade with prolonged sun-exposure. Many of today's inexpensive or free totes are often made from recycled matter, from minimally-processed natural fibers, or from byproducts of processes that refine organic materials.
