100% natural and environmentally friendly material. Hemp is one of the strongest and most durable of all natural textile fibres. Not only is hemp strong, but it also holds its shape, stretching less than any other natural fibre. Hemp may be known for its durability, but its comfort and style are second to none. The more hemp is used, the softer it gets. Hemp doesn't wear out, it wears in. Hemp is also naturally resistant to mold and ultraviolet light.
