Soft-shell luggage is made from flexible materials like nylon or polyester, allowing it to be lightweight and easy to maneuver. This type of luggage often features external pockets for quick access to essentials and can expand to accommodate extra items. Unlike hard-shell luggage, which is rigid and offers more protection, soft-shell luggage can be squeezed into tight spaces, making it ideal for travel on planes, trains, or buses. It is also generally more affordable and comes in various styles and colors, catering to different preferences and needs.
