While zipperless (latch-style) luggage offers superior security and a sleek look, it has several notable disadvantages in 2026. First is the lack of expandability; unlike zippered suitcases that often have a fabric gusset to add 20% more space, a zipperless aluminum or polycarbonate shell has a fixed volume. If you overpack, the latches may not close at all. Second is the weight; the metal frames and heavy-duty latches required for a secure seal typically make these bags 2–4 pounds heavier than their zippered counterparts, which can be a problem with strict airline weight limits. Third, if the metal frame gets slightly bent or dented during rough baggage handling, the latches may fail to align, making the suitcase impossible to close or lock securely. Finally, zipperless luggage is generally more expensive to purchase and repair. For travelers who value security against the "pen trick" (where zippers are easily breached), these trade-offs are often worth it, but they require a more disciplined approach to packing.
