For twenty-six years I have made my living telling other people how to pack a bag. You would think that would make me good at it. It did not. The night before a flight, I would sit on the bedroom floor at eleven o'clock with three piles of clothes, a box of zip-top bags, and a carry-on that would not close without a knee on the lid.

Two years ago that changed, and it changed because of something small. The same week I bought the Samsonite Omni PC carry-on I still travel with, I ordered a six-piece set of BAGAIL packing cubes. I had packed in zip-top bags and rolled clothes since the nineties. I expected to be mildly less annoyed. I did not expect to stop dreading the night before a trip.

A hand lifting a zippered packing cube from an open suitcase into a hotel dresser drawer that already holds other cubes.

The first real test was a spring trip to Portugal. Eleven days, one carry-on, and a rental car with a trunk the size of a bread box. I laid the six cubes out on the bed the way I lay out a client's itinerary. Shirts in one. Trousers in another. Underthings and socks in a third. Chargers, the plug adapter and my reading glasses in a fourth, the one that stays in my tote. Then I zipped them and set them into the bag like books on a shelf.

Here is the part I did not see coming. In the hotel I stopped unpacking. I opened the dresser drawer, lifted the cubes out of the suitcase one at a time, and set them inside. Ten seconds each. My clothes were in a drawer, still sorted, and the empty bag went up on the luggage rack. In the old days I spent twenty minutes moving stacks of folded shirts from a suitcase to a shelf, then spent the last morning of the trip putting them all back.

Walt noticed on the second morning. He is sixty-five, retired, and packs his own bag without commentary. He watched me pull a shirt out of a cube without disturbing anything under it and said, 'Do that for mine next time.' He meant it as a joke. He also meant it. On our short domestic trips we share the Samsonite, and now two of the six cubes are his.

Eleven days in Portugal, one carry-on, and I never once had to kneel on the lid.

The Six Pieces I Now Pack Before Anything Else

Six zippered nylon cubes with a handle on each, and the whole set weighs 10.4 ounces. Mine have been in the bag on every trip for two years. If your suitcase still ends up on the floor at eleven at night, start here.

I read labels. It is a habit from the travel business, where a supplier will tell you a room sleeps four and mean two adults and two very small children. The BAGAIL set is nylon, closed with zippers, rectangular, with a handle on each piece. The listing gives the dimensions as 17.32 by 13.78 by 3.94 inches and the weight of the whole set as 10.4 ounces, which is lighter than the paperback I carry on the plane. Load capacity is listed at fifty pounds. I have not tested that and I do not intend to. A carry-on that heavy stops being a carry-on.

Two years and about eight trips later, the zippers still run. Nothing has torn. Nothing gets lost in the bag anymore because nothing comes out of the bag loose. What I notice most is not the packing. It is the searching. I know which cube holds the phone charger and which one holds the spare reading glasses, and I can find either one in a rented apartment at six in the morning without turning on a light.

I take security more seriously than I did at forty. At the checkpoint I pull out the one cube with the liquids bag and the electronics, and everything else stays zipped inside the suitcase. No loose socks rolling down the conveyor. No repacking on a bench with my back to the room. I say a quiet prayer before every long flight, and I would rather say it about a bag that is already in order.

Two things I will tell you straight. The first is that a cube holds what it holds. Overstuff one and it stops being a cube and becomes a rock, and the zipper is the part that pays for it. The second is that these are not vacuum bags. I have never used vacuum compression bags, though plenty of my clients swear by them. What I know is that I am not spending the last morning in Venice hunting for a vacuum cleaner. I would rather fold a shirt twice and find it where I left it. One cube is the dirty-clothes cube from day three onward. That is the entire system. It is not clever. It just means I am never standing over an open suitcase at the end of a trip trying to remember which pile is clean.

People ask me for packing advice the way people ask a dentist about teeth. Nine times out of ten they are not asking about folding. They are asking why the bag betrays them at the last minute, and the answer is usually that nothing in it has a home. The BAGAIL cubes fit both bags in this house, the Samsonite on longer trips and Walt's older softside on the short ones. That matters more than it sounds like it should. I do not re-plan the packing when the bag changes. I move the cubes.

What I'd Tell You If We Were Sitting at My Kitchen Table

The night-before scramble is not a packing problem. It is a decision problem. You are deciding where things go while you are tired, and tired people make poor decisions with a suitcase. Decide once, in daylight, with the cubes empty on the bed, and then the bag goes together the same way on every trip. I have planned other people's trips for twenty-six years and I still had to learn that for myself. Start with one trip. If it does not make your last morning easier, you have lost nothing but an hour of folding.

Two Years In, This Is Still the First Thing I Pack

Six nylon cubes, zippered, 10.4 ounces for the set, and a handle on each one. Mine have been to Portugal, Ireland and every short trip since. The packing is quieter now, and at sixty-three I will take quiet where I can get it.
