Because softshell luggage has more give, a hard shell suitcase can be better at protecting fragile contents, assuming you cushion it well inside. On the other hand, that rigid exterior makes hardshell bags unable to be compressed to squeeze into tight spaces like softsided bags are more apt to allow.

The choice between a soft-sided or hard-sided carry-on in 2026 depends on your packing style and the type of aircraft you usually fly. Soft-sided luggage is generally superior for "over-packers" and those flying on smaller regional jets; the fabric has "give," allowing you to stuff in extra items, and the exterior often features accessible pockets for tablets or boarding passes. Crucially, a soft bag can be squished into tight overhead bins or under seats more easily than a rigid shell. On the other hand, hard-sided luggage (made of polycarbonate or aluminum) offers much better protection for fragile items and is typically more "weatherproof" if you are caught in the rain on a tarmac. Hard shells are also more secure against theft, as they cannot be easily slashed with a blade. However, hard bags often use a "clamshell" opening, which requires twice the floor space to pack or unpack, whereas soft bags usually have a single "lid" opening. For the frequent traveler who values efficiency and external pockets, soft-sided remains the practical favorite, while the style-conscious traveler who wants to protect their gear often opts for the sleek, protective hard shell.
