Soft-shell suitcases are made from flexible materials like nylon or polyester, allowing them to be lightweight and easy to maneuver. They often feature external pockets for quick access to essentials and can expand for extra packing space. This design makes them ideal for travelers who need to fit more items without the bulk of a hard case. These suitcases typically have padded interiors to protect belongings and may include wheels and telescoping handles for easy transport. While they may not offer the same level of protection as hard-shell suitcases, soft-shell options are often more affordable and versatile for various travel needs.
