Not reliably. There’s a real tendency for thicker, more impact-resistant shells to weigh more, so weight and durability do correlate to a degree — but some of a case’s weight can come from decorative hardware, an inefficient internal frame, or simply a less refined manufacturing process rather than genuine reinforcement where it matters.
Two cases of similar weight can differ meaningfully in actual durability depending on where that weight is distributed — reinforcement concentrated at stress points like wheel mounts and handle housings matters more than the same total weight spread evenly and less usefully across the shell.
Rather than judging by weight alone, checking the specific shell material, the handle’s stated load rating, and long-term owner reports about wheel and zip failures gives a more reliable picture of genuine durability than an empty-weight figure by itself.
