Packing for Zero-G: What Actually Stays in Your Bag

Twenty years of transfer flights taught me what's worth the weight allowance and what just floats around annoying everyone.

Every departure briefing includes a packing list, and every departure I watch someone ignore half of it. I get it. Zero-G travel doesn't feel real until you're in it, and until then a packing list is just a piece of paper.

Start with clothing that doesn't need much care. Zero-G laundry is a whole procedure nobody wants to learn on day two of a twelve-day cruiser, so pack synthetic blends that dry fast and don't wrinkle when they've been floating loose in a cabin locker.

Bring fewer shoes than you think you need. On a pressurized cruiser you're barely on your feet — most of the trip is handholds and straps — and the extra pair is just weight you're paying for twice, going out and coming back.

A save-a-trip kit matters more off-world than it ever did on a beach vacation: spare O-ring seals if your itinerary includes any EVA work, electrolyte tablets for the first day of adjusting to cabin pressure, and something to read that doesn't need a screen, because screens and prolonged weightlessness do not get along for everyone.

The one thing I tell every group, every time: bring less than the list allows, not more. You'll be handed gear at every stop that you didn't know existed. Leave the room.
