When considering check-in luggage options, a hard case presents the advantage of increased protection for more fragile items within. The sturdy material resists crushing from external impacts, reducing the likelihood of breakage. However, a low quality zipper mechanism may tear easily, leading to potential spillage of the contents while the shell remains intact. It should be noted that hard cases are susceptible to scratches and other cosmetic damage due to rough handling by luggage handlers. Luggage with soft sides is more resistant to showing scratches. However, they are prone to seams tearing when crushed and puncture. They offer far less protection from inclimate weather and for fragile items within.
