Samsonite utilizes several high-tech materials for its hard-shell luggage, depending on the specific collection. Their most premium and famous material is Curv® technology, which is made by weaving layers of polypropylene fibers together and then hot-pressing them to create an incredibly thin, lightweight, but virtually indestructible shell. This material is exclusive to Samsonite in the luggage industry. For their more standard hardside lines, they typically use 100% Polycarbonate, a high-impact-resistant plastic that is flexible enough to absorb shocks without cracking. Some of their more budget-friendly or "rugged" lines utilize ABS (Acrylonitrile Butadiene Styrene) or a "Polycarbonate/ABS" blend to provide a balance of durability and cost-effectiveness. In 2026, Samsonite has also introduced Recyclex™, a shell material made from 100% recycled post-consumer plastic bottles, reflecting a brand-wide shift toward sustainability without compromising the structural integrity the brand is known for.
