04 — Carry-On / Guide

What to pack in a carry-on

The quantities barely change with trip length. What changes is the climate, and the plan for washing things.

By Brijon M.Last updated How we pick
Clothes and toiletries laid out ready to pack into a carry-on

The short answer

Pack four or five tops, two bottoms, four or five sets of underwear and socks, one mid layer, one shell and two pairs of shoes -- wearing the bulkier pair. Those quantities cover a weekend or three weeks; what changes is climate and whether you plan to wash.

01 — Core list

The quantities that do not scale

This is the counterintuitive part. Once you accept doing laundry, the packing list for a weekend and for three weeks is close to identical, because you pack for the interval between washes rather than for the number of days.

ItemQuantityNote
Tops4 to 5One palette, so every top works with every bottom
Bottoms2One worn, one packed. Dark and versatile
Underwear and socks4 to 5Merino or synthetic, so they wash and dry overnight
Mid layer1Fleece or light insulation
Shell1Waterproof and packable, worn on the flight
Shoes2Wear the bulkier pair
Sleepwear1Or a clean base layer doing double duty
Laundry kit1Detergent sheets, sink plug, cord. Weighs nothing

02 — Two or three days

What a weekend genuinely needs less of

A weekend is the one case where you can skip the laundry plan, and the list shrinks slightly rather than scaling down proportionally.

  • Two tops, one spare bottom, three sets of underwear and socks
  • One layer and a shell -- the same as any trip, because weather does not care about trip length
  • One pair of shoes, worn, unless the trip includes something specific
  • Toiletries decanted into the smallest containers you own
  • No laundry kit, and no spare bag
  • Everything that matters in the personal item, as always. See carry-on essentials

03 — A week or more

What a longer trip adds

Almost nothing, and that is the point. The additions are plans and redundancy rather than more clothes.

  • A laundry plan. Sink washing nightly for a week; a laundromat stop for longer. Look up where they are before you need one.
  • Slightly more robust footwear. You will walk further in total, and a shoe that is fine for three days can be uncomfortable by day ten.
  • Spares of the things whose failure would be a problem: a charging cable, a pair of glasses, any critical medication.
  • A packable spare bag, if it folds into its own pocket, for what you buy.
  • Printed copies of reservations, because phones die and coverage fails at check-in desks.
  • Not more clothes. Fourteen t-shirts is not a longer trip, it is a checked bag.

04 — By climate

Climate changes the list far more than length

Hot and humid

Linen and technical synthetics over cotton, because cotton holds sweat and stays damp. More tops than the base list, since you will change more often, and fewer bottoms. A sun hat and a long-sleeved sun layer, which cover better than repeated sunscreen application.

Swimwear doubles as a second set of light clothing, and it dries in minutes. Expect to wash more often, which makes the fast-drying fabric choice matter more rather than less.

Cold

This is where layering earns its place: a merino base, a mid layer and a shell cover a far wider range than one thick coat, and they pack smaller than the coat does. Wear the bulkiest items on the flight.

Add a warm hat, gloves and thicker socks -- all small, all disproportionately effective. Cold-weather packing is also where compression cubes genuinely help, because knitwear and insulation are the only things with real air to squeeze out.

Mixed or shoulder season

The hardest case, and layering is the entire answer. Pack for the coldest part of the forecast using layers rather than packing two separate wardrobes, and accept that you will be slightly overdressed or underdressed at the extremes.

Check the forecast for your actual dates and destination elevation shortly before you leave rather than relying on seasonal averages, which hide the range.

A trip with a formal element

One smarter item at most, and preferably one that works with what you already packed -- a shirt that goes with your travel pants, a dress that works with the shoes you brought. Two pairs of shoes is the limit, so the smart option has to be one of them or has to work with a neutral pair.

If the formal element is substantial, that is the point at which a carry-on stops being the right answer and a checked bag is a reasonable decision rather than a failure.

05 — Method

The packing order

Order matters for whether the bag closes and for whether it stays packed neatly when it is handled.

  1. 01Shoes at the wheel end, or against your back in a pack. They are the heaviest and bulkiest items, and weight belongs low and close to you.
  2. 02Fill the inside of the shoes with socks, chargers and small bottles. This is the most commonly wasted space in any bag.
  3. 03Rolled knits in cubes next. Rolling compresses soft fabrics for free and resists creasing.
  4. 04Structured items flat on top -- shirts, anything you do not want creased, in a single layer rather than folded into a cube.
  5. 05The liquids bag last and accessible, or better, in the personal item so security does not mean unpacking.
  6. 06One cube left empty for worn clothes, so the clean side stays clean.

06 — What to cut

The common over-packs

  • A third pair of shoes. Almost always carried unworn, and the biggest single volume saving available.
  • Clothes for weather that is not forecast. Check the actual dates. You can buy a sweater almost anywhere.
  • One outfit per day. This is the habit the whole list exists to replace.
  • Full-size toiletries. Mostly plastic and air, and they fail the liquids rule.
  • A hair dryer. The hotel has one, and single-voltage appliances are the most commonly destroyed thing in travel.
  • Books, plural. One, or an e-reader.
  • Anything you have not worn in the last month at home. You will not wear it abroad either.

Best for cold-weather packing

Peak Design Packing Cubes

Compression genuinely helps with knitwear and insulation, which is what a cold-weather list is made of.

Compression is worth it only where there is air to remove, which means cold-weather knitwear and insulation. For a summer list of t-shirts it is just heavier cubes. See <a href="/carry-on/packing-cubes-vs-compression-bags">cubes versus compression bags</a>.

Specs

  • Two-stage compression zipper
  • Internal divider for clean and worn clothes
  • Weather-resistant recycled nylon
  • Several sizes

Good for

  • Real volume saving on sweaters, fleece and insulation
  • The clean and dirty divider solves a genuine problem
  • Works the same way on the return journey, unlike vacuum bags

Bad at

  • Several ounces heavier per cube than plain ones
  • No benefit on shirts, shoes or toiletries
  • Compressed clothes crease more

Best for the bag the list goes in

Osprey Farpoint 40

Clamshell opening and a real hipbelt. Buy the bag before the cubes, not after.

Measure the interior of your bag before buying cubes, because cubes that leave dead space waste more than they organize. That is why the bag is the first purchase. See <a href="/carry-on/best-travel-backpacks">travel backpacks</a> and <a href="/carry-on/best-carry-on-luggage">carry-on luggage</a>.

Specs

  • Roughly 40 liter capacity
  • Full clamshell opening
  • Load-transferring hipbelt that stows away
  • Padded laptop sleeve

Good for

  • Opens flat, so you pack in sections and live out of it
  • A genuine hipbelt, which most travel bags lack
  • Harness stows so straps do not catch in baggage systems

Bad at

  • Forty liters exceeds the strictest airline limits when packed full
  • Minimal internal organization
  • No front stretch pocket

Best for the fabric that makes the quantities work

Darn Tough Hiker Micro Crew Cushion Socks

Merino resists odor and dries overnight, which is why four pairs covers any trip length.

The quantities in the table at the top only work if the fabrics cooperate. Merino and technical synthetics resist odor and dry overnight; cotton does neither, which is the real reason it is a poor travel fabric.

Specs

  • Merino wool blend
  • Seamless construction
  • Cushioned sole
  • Unconditional lifetime warranty

Good for

  • Can be worn more than once without becoming unpleasant
  • Washes in a sink and dries by morning
  • Lifetime warranty keeps the cost per year low

Bad at

  • Expensive per pair
  • Eventually wears at the heel
  • Warmer than synthetic for hot climates

Questions

Frequently asked

How many clothes should I pack in a carry-on?
Four or five tops, two bottoms, four or five sets of underwear and socks, one mid layer and one shell. Those quantities cover a weekend or three weeks, because you pack for the interval between washes rather than the number of days.
What should I pack for a week in a carry-on?
The core quantities above plus a laundry kit -- detergent sheets, a universal sink plug and a length of cord, which together weigh almost nothing. A week and a weekend need nearly the same clothes once you accept washing things.
How does climate change what I pack?
More than trip length does. Hot and humid means more tops and fast-drying fabrics; cold means layering a base, mid and shell rather than one thick coat; mixed means layering and checking the actual forecast for your dates rather than seasonal averages.
What order should I pack a carry-on in?
Shoes at the wheel end or against your back, with small items packed inside them. Rolled knits in cubes next. Structured items flat on top in a single layer. Liquids last and accessible, or better, in your personal item so security does not mean unpacking.
What do people most often over-pack?
A third pair of shoes, clothes for weather that is not forecast, and one outfit per day. All three are the same mistake -- packing for possibilities rather than for the forecast and a wash cycle. Shoes are the biggest single volume saving available.
