Carry-On Packing Guide: How to Travel With Only a Carry-On Backpack

Checked luggage is a scam. A slow, expensive, nerve-shredding scam that costs you time, money, and at least one frantic twenty minutes at baggage claim watching a sad, battered suitcase that isn't yours do laps on the carousel.

The good news? You don't need it. With the right mindset – and the right gear – you can pack everything you need for a one to two-week trip into a single carry-on backpack.

This guide is here to show you how. We'll cover the rules, the strategy, the carry-on packing list, and – most importantly – the gear that earns its spot in your bag.

Carry-On Packing Mindset Shift 

It’s important with carry-on packing you don’t go into it thinking of all the things you won’t be able to take with you. You’ll just end up a sad, sad human. Instead, think of it as a mindfulness exercise. Every item you pack should earn its spot. 

The golden question to ask before packing anything: "Does this earn its place?" If an item only does one job, leave it at home. Choose gear that multitasks – a towel that's also a beach blanket, a puffy blanket that works on the plane and at the campsite. 

The other mindset shift is accepting that you'll re-wear things. Travellers who've mastered carry-on-only living will tell you: nobody notices what you're wearing. Everyone's too busy looking at their own Instagram.

The Carry-On Rules You Need to Know

Before you start stuffing your bag, it helps to know the actual limits. Carry-on size rules vary by airline, but the common standard most airlines work to is around 56cm x 36cm x 23cm – though budget carriers often go smaller. Always check your specific airline before you fly.

Weight limits are where it gets trickier. Full-service carriers generally allow 7–10kg for carry-on. Budget airlines can be stricter. Weigh your packed bag at home before you leave. Future you will be grateful.

Liquids still follow the 100ml rule for most international flights: containers of 100ml or less, all fitting into a single one-litre clear zip-lock bag. 

How to Choose Your Travel Bag

Your bag is the foundation of this whole exercise, so it's worth spending some time here. A backpack in the 30–40 litre range is the sweet spot for carry-on travel – big enough to hold two weeks of thoughtfully packed gear and small enough to fit in overhead bins.

Our travel backpack is built exactly for this. At 30 litres and just 325 grams, it folds into its own 20cm x 15cm pouch when empty – which means it doubles as a packable day bag once you've arrived. Here are all the other epic features:

• Lightweight construction. At 325 grams, every gram goes toward your stuff, not the bag carrying it.

• Water-resistant material with a YKK waterproof zipper. It'll handle a rain shower, condensation, or a splash without complaint.

• Heaps of pockets. A front zip pocket, a front easy-access pouch, two external bottle holders, an internal pouch, and a key clip (so everything has a place and nothing goes mysteriously missing).

• Comfort built in. Padded shoulder straps, breathable mesh back panel, and a removable waist strap for longer wear days.

• Genuinely good for the planet. Made from 12 recycled post-consumer plastic bottles, B Corp certified, and four trees planted in Nakie's Kenya reserve for every one sold.

Nakie's tote bag also deserves a mention here — it folds down to almost nothing and makes the perfect secondary day bag once you've arrived. Weighing just 655 grams and holding 45 litres when open, it's the perfect carry-on bag. 

The Carry-On Packing List: What Actually Makes the Cut

Now, obviously, this is a framework and not a prescription. You'll need to adjust this list for your climate, trip length, and the number of times you're willing to do laundry.

Clothing Packing List 

The carry-on packing philosophy for clothes comes down to one principle: fewer items, better quality, neutral colours that mix and match. Aim for a capsule wardrobe that can go from day to dinner without a full outfit change.

A two-week packing list looks something like this:

• 3–4 tops (2 t-shirts, 1 lightweight long-sleeve, 1 slightly nicer shirt for evenings)

• 2 bottoms (1 pants/jeans that can dress up or down, 1 shorts or skirt depending on climate)

• 1 light layer (a packable jacket, hoodie, or merino cardigan)

• 5–7 pairs of underwear (merino wool if budget allows — it resists odour and dries fast)

• 3 pairs of socks

• 1 pair of shoes on your feet, 1 pair of sandals or lightweight flats in your bag

• Swimmers/activewear if relevant to your trip

The key is choosing fabrics that pack small, dry quickly, and don't wrinkle badly. Linen, merino, nylon blends, and technical fabrics all work well (heavy cotton is the enemy of the carry-on traveller). 

Toiletries

This is where most people over-pack. Be ruthless. If it's not something you'll use every single day, it probably doesn't need to come.

• Solid shampoo bar, conditioner bar, soap (all under 100ml restrictions, all last longer than liquids)

• Toothbrush, toothpaste (travel size or tabs)

• Deodorant – crystal or solid format if you're flying frequently

• SPF moisturiser (does double duty as both skincare and sun protection)

• A small, foldable toiletry bag to keep it all contained

Tech and Cables

Keep it tight. Most travellers use maybe 60% of the tech they pack.

• Phone + charger

• Universal adaptor (one good one, not three mediocre ones)

• Earbuds or headphones

• Laptop or tablet if necessary for work (not just "in case I get bored")

• A small cable organiser or zip pouch for cables
  

If you're travelling for leisure, seriously consider whether the laptop needs to come at all. Phones handle most things now, and leaving the laptop behind is genuinely liberating.

The Extras That Earn Their Place

There's a category of travel gear that sounds optional right up until the moment you desperately need it. These items consistently prove their worth:

• A compact, quick-dry, sand-free towel 

• A lightweight blanket or compact puffy layer for long flights and cold buses

• A dry bag or waterproof stuff sack for beach days, boat trips, and unpredictable weather

• A reusable water bottle with a filter

• A small first aid kit: plasters, pain relief, antihistamines, motion sickness tablets

Packing It All In (The Practical Bit)

Once you've curated the right gear, the packing itself becomes almost enjoyable. A few techniques that actually help:

• Roll, don't fold. Rolling clothes is more compact and causes fewer creases. Rolling tightly is even better for t-shirts and pants.

• Use packing cubes. They compress your clothing, keep things organised by category, and make it possible to actually find things in your bag without unpacking everything.

• Wear your heaviest items on travel days. Boots, a jacket, jeans – things that take up the most space should be on your body when you're at the airport, not in your bag.

• Pack to a weight limit, not a space limit. If your carry-on weighs 11kg but the limit is 7kg, packing cubes won't save you. Weigh your bag.

• Shoes go in first, soles against the back panel. They're your heaviest items and they set the structure for everything else. Stuff socks inside them to save space.

• Quick-access things go in last or in exterior pockets. Passport, charger, anything you'll need on the plane – right where you can reach it.

What to Leave at Home (No Matter How Much You Think You'll Need It)

A note on the items that end up at the bottom of every bag, untouched:

• The "nice" outfit for a nice dinner that never happens

• Three books (bring an e-reader or just one, and be okay leaving it in a hostel book exchange)

• A full-size hairdryer (accommodations almost always have one; if not, embrace air-dry)

• Backup shoes for every conceivable activity

• A travel iron (wrinkle-resistant fabrics exist for exactly this reason)

• Anything you're bringing "just in case" that you haven't used on your last three trips

The hardest part of carry-on travel is the edit – deciding what to leave behind. But every seasoned carry-on traveller will tell you the same thing: you almost never wish you'd brought more. You almost always wish you'd brought less.

The Travelling Light Payoff

There's a moment that every carry-on convert remembers. It usually happens in an airport, when the people around you are queuing for checked bag drop or standing miserably at baggage claim, and you're already through security with a coffee, or already outside in the sun.

That moment is the whole argument. It doesn't take much to get there – just a bit of intentional packing, the right gear, and the willingness to leave the hotel-lobby-dinner outfit at home.

Travel lighter. Arrive sooner. See more. And if you can do it with gear made from recycled plastic that also plants trees? Well, that's just a bonus.

FAQs

Can I really travel for two weeks with just a carry-on backpack?

Yes – and once you do it, you'll wonder why you ever checked a bag. The key is choosing versatile, quick-dry clothing in neutral colours, packing multi-use gear, and accepting that toiletries are available everywhere humans travel. Two weeks is very doable. Some people do months.

What size backpack do I need for carry-on travel?

A 30–40 litre backpack hits the sweet spot for carry-on travel. It's large enough to hold two weeks of thoughtfully packed gear and small enough to fit in most overhead bins. Always check your specific airline's carry-on dimensions before you fly – budget carriers can be ruthless. 

How do I keep my carry-on under the weight limit?

Weigh your packed bag at home before you leave. This is the single most useful thing you can do. Choose lightweight fabrics and gear, wear your heaviest items on travel days (boots, jacket, jeans), and be honest about what you actually use versus what you pack "just in case."

What's the best travel towel for carry-on travel?

You want something lightweight, quick-dry, compact, and large enough to be useful. Nakie's Recycled Sand Free Beach Towel ticks every box – it's 160cm x 90cm, weighs 740 grams, and packs into its own waterproof bag. It works at the beach, the hostel, and everywhere in between.

Do I need packing cubes?

They're not strictly necessary, but they make a pretty big difference. Packing cubes compress your clothing, keep categories organised, and mean you can find things without unpacking your entire bag. If you're committing to carry-on-only travel, they're worth the small investment.

What should I never pack in a carry-on?

Anything sharp or prohibited by aviation security, obviously. Beyond that: full-size liquids over 100ml, a full-size hairdryer, more shoes than you can realistically wear, and anything you're bringing "just in case".
