Hard-sided luggage is usually constructed from high-density plastic or lightweight metal, and is designed for durability and security. Hardsided luggage is easy to use because the cases often lack the numerous straps and latches found on fabric pieces, resulting in fewer snags and less damage during transit. The rigid cases offer the greatest protection for fragile items, and will not become saturated with moisture. They also retain their original shape and integrity, even after extended use. Rigid baggage is available in a wide range of shapes and colors.
