Eighteen by fourteen by eight inches is the number that decides this category. It's the sizer box the fee-charging airlines use at the gate, and plenty of bags sold as personal items are cut just generously enough to need a shove. The ZOMFELT is built to those exact dimensions — 32 liters of body, a padded sleeve that takes a 17.3-inch laptop, and a shape that slides under the seat without an argument. That single decision is why it's our top pick.
Open it and the case gets stronger. The main compartment unzips 180 degrees and lies flat, so you pack it like a small suitcase instead of mining a tube for a clean shirt. There's a lined wet pocket for a damp swimsuit or a leaky toiletry bag, eight pockets in total, and padded adjustable straps that sit where they should once the bag is full. It's under two pounds empty, which matters by the third terminal.
The 14-inch width is the thing to pack around. It's the widest body here, and a bulging front pocket is what turns a sure thing into a gate-check negotiation — keep the outer pockets for flat items, put the bulk in the main compartment, and it behaves. We came away thinking of it as the bag for the traveler who wants one pack to do the under-seat job on a three-day trip without paying premium money for it.
