The suitcases in Samsonite's S'Cure collection are known for their rock-solid exterior. They're made of polypropylene, providing optimal protection for your luggage. On top of that, the suitcases have an integrated, waterproof click lock. The inside features a zipper compartment to separate your clothes from your other luggage. The suitcases roll smoothly over the ground, thanks to the double wheels that rotate 360 degrees.
