Samsonite's hardside luggage in 2026 is primarily constructed from three advanced materials: Polycarbonate, Polypropylene, and Roxkin™. Polycarbonate (used in the Omni and Voltage lines) is the most popular choice because it is incredibly impact-resistant; when it takes a hit, it "flexes" and pops back into shape rather than cracking. For those seeking the absolute lightest weight, Samsonite uses Polypropylene, specifically through their patented Curv® technology, which involves weaving polypropylene fibers to create a material that is exceptionally strong yet light enough to lift with a single finger. The newest innovation, Roxkin™, is a multi-layered material developed to be virtually indestructible while maintaining a slim profile. All these materials are chosen for their ability to protect fragile contents from the rigors of automated baggage handling systems. Additionally, most modern Samsonite shells now feature a "micro-diamond" or "sand-blast" texture, which is engineered to hide the scuffs and scratches that inevitably occur during international travel, keeping the luggage looking newer for a longer period.
