Samsonite utilizes a variety of high-performance materials, but its most famous proprietary technology is Curv® material. Used in their premium "C-Lite" and "Lite-Shock" collections, Curv is made from woven layers of polypropylene, which are then heated and pressed to create a shell that is exceptionally light (a carry-on can weigh just 4.5 lbs) and virtually indestructible. It is unique because it can "pop" back into shape even if crushed or dented during transit. For their mid-range and soft-side luggage, Samsonite often uses 100% Polycarbonate (for hard shells) or high-denier Ballistic Nylon (for soft shells). In 2026, many of their newer lines feature Recyclex™, a fabric made from 100% post-consumer recycled PET bottles, catering to the growing demand for sustainable travel gear without compromising the brand's reputation for durability and impact resistance.
