A hardshell suitcase is typically better than a softside bag for protection (as long as your items are packed safely inside, too). However, all hardshell materials are prone to getting scuffed, scratched, or possibly cracked more so than with fabric suitcases.

Yes, hard shell luggage can and does break, although its durability has improved significantly by 2026. Hard shell bags are typically made from materials like Polycarbonate, ABS (Acrylonitrile Butadiene Styrene), or Aluminum. While aluminum is incredibly strong, it can be prone to permanent "dents" that look unsightly over time. ABS is the least expensive but most brittle, often cracking under extreme impact or low temperatures in the aircraft's hold. Polycarbonate is the "gold standard" for flexibility; it is designed to "flex" and pop back into shape, making it highly resistant to cracking. However, even the most expensive hard shell bags can suffer from "stress fractures" at the corners or around the wheel housings if they are mishandled by baggage systems or crushed under heavier bags. Additionally, hard shell bags are more prone to scuffing and scratching compared to soft-sided nylon luggage. To prevent breakage, travelers should invest in "100% Polycarbonate" rather than "PC/ABS blends" and look for reinforced corner guards to protect the most vulnerable areas.
