Hard luggage, also known as hard-shell luggage, is made from materials such as polycarbonate, aluminum, or ABS plastic. It offers a high level of protection for your belongings as it is impact-resistant and waterproof. Hard luggage is also easy to clean and can be more secure as it often comes with built-in locks. Soft luggage, also known as soft-shell luggage, is made from materials such as nylon, polyester, or canvas. It is lightweight and more flexible than hard luggage, which can make it easier to fit into tight spaces. Soft luggage also usually has more compartments and pockets for organizing your belongings.
