The Ultimate Carry-On Only Packing List (For Any Trip, Any Climate)

The moment I stopped checking luggage, travel became fundamentally better. No waiting at baggage claim. No $35 bag fees each way. No lost suitcase nightmares. No being held hostage to a hotel before 3pm check-in. Just me, a carry-on, and the freedom to move.

I've done this for trips ranging from 4-day weekend getaways to 6-month backpacking trips. This list works for all of them.

The Core Philosophy: Pack for One Week, Travel Forever

The secret isn't owning less — it's owning the right things. Specifically: items that layer, items that pack small, and fabrics that dry overnight so you can re-wear and re-wash without smelling like a traveler.

The rule I use: 7 shirts, 5 bottoms, 7 underwear, 4 socks — maximum. Everything fits in one carry-on. Add laundry every 5–7 days, and you can travel indefinitely.

The Bag

Your bag is the most important purchase. Get this wrong and nothing else works.

I've used the Osprey Farpoint 40 for years — it's a 40L travel backpack that fits in almost every airline's overhead bin, converts to a daypack, and has a dedicated laptop sleeve. At under $200, it's outstanding value.

For a more luggage-style approach, the Away Carry-On is sleek, TSA-approved lock, and handles like a dream on cobblestone streets.

Clothing

Tops

• 3 x merino wool t-shirts (Wool& or Unbound Merino — expensive upfront, pay for themselves in laundry savings)
• 2 x button-down shirts (one can double as light jacket/layer)
• 1 x lightweight long-sleeve (for cool evenings or conservative dress requirements)
• 1 x nicer going-out top or blouse

Why merino wool? Odour-resistant, temperature-regulating, and wrinkle-resistant. You can wear a merino t-shirt 3–4 days in warm weather before it needs washing. Nothing else comes close.

Bottoms

• 2 x travel pants (Bluffworks Gramercy or Outlier Slim Dungarees — lightweight, wrinkle-free, look smart)
• 1 x shorts (doubles as swimwear if quick-dry)
• 1 x jeans (if absolutely necessary — heavy, slow to dry, usually skip these)
• 1 x leggings or yoga pants (lounging, long flights, cooler destinations)

Underwear & Socks

• 5 x merino wool underwear (ExOfficio or Smartwool — worth every penny)
• 4 x merino wool socks
• 1 x compression socks (long-haul flights only)

Shoes (the hardest part)

• 1 x versatile everyday sneaker (I use Allbirds Tree Runners — lightweight, packable, look decent with everything)
• 1 x sandals or flip-flops (for hostels, beaches, casual days)
• Optional: 1 x dressy flat or loafer

Three pairs of shoes maximum. You're wearing one, you're packing two.

Toiletries & Health

Go solid where possible (no liquid restrictions, less spillage):

• Solid shampoo bar (Ethique or Lush)
• Solid conditioner bar
• Solid body wash
• Travel toothbrush + small toothpaste
• Deodorant (solid stick, not aerosol)
• SPF 50 face sunscreen (small tube — refill locally)
• Moisturiser (solid balm or small tube)
• Razor + 2 replacement blades
• Any prescription medication (in original packaging, in carry-on — never check)
• Small first aid kit: plasters/band-aids, ibuprofen, Imodium, antihistamine, antiseptic wipes

Pro tip: Buy toiletries locally in your destination. This reduces what you carry and avoids the liquids restriction entirely. Most travelers can fly with just a stick of deodorant and a solid shampoo bar.

Tech Essentials

• Laptop (if needed — I use a MacBook Air 13")
• Phone + charger cable
• Portable power bank (20,000mAh — never be stranded with a dead phone)
• Universal plug adapter (one compact travel adapter covers most of the world)
• Kindle or reading app (replaces heavy books)
• Noise-cancelling headphones (AirPods Pro or Bose QC45 — life-changing on long flights)
• Memory card + small card reader (if you shoot photos)

One cable to charge as many devices as possible. If you have USB-C across your laptop, phone, and power bank, one good cable manages everything.

Documents & Money

• Passport (keep a digital photo backup in cloud storage)
• Physical copies of travel insurance, key bookings, and emergency contacts — in a separate pouch
• 2 debit cards from different banks (one as backup)
• 1 credit card with no foreign transaction fees (see credit card guide above)
• Small amount of local cash — enough for a taxi from the airport before you find an ATM
• Travel wallet or slim card holder (not a bulky wallet)

Packing System

Packing cubes are non-negotiable. They transform a chaotic bag into a system:

• Large cube: Clothes
• Medium cube: Underwear and socks
• Small cube: Electronics cables and adapters
• Toiletry bag: Solid toiletries + meds

Roll your clothes, don't fold. Rolling compresses items and reduces wrinkles. Stuff the gaps (rolled socks inside shoes, etc.).

What to Leave at Home

• Hair dryer (hotels and hostels almost always have one)
• Full-size towel (quick-dry microfibre travel towel weighs nothing)
• Books (Kindle)
• "Just in case" items (you'll never use them)
• More than 3 pairs of shoes
• More than one "nice" outfit

The hardest lesson in carry-on travel: you will buy things you forgot. Local pharmacies and supermarkets exist everywhere. You don't need to pack for every contingency.

Carry-on travel takes one or two trips to get right. The first time, you'll probably overpack and struggle. By the third trip, you'll wonder how you ever checked a bag. The freedom is genuinely life-changing.
