When selecting a suitcase, consider factors like durability, size, and weight. A lightweight but strong material, such as polycarbonate, is ideal. Opt for a suitcase with four wheels for smooth mobility and a TSA-approved lock for security. Expandable luggage can be useful if you plan on bringing back souvenirs. Hard-shell suitcases protect fragile items better, while soft-shell ones allow more flexibility. A well-structured ensures convenience, comfort, and durability, making your trips hassle-free. Investing in a high-quality suitcase saves you from frequent replacements and enhances your overall travel experience.
