Capsule Wardrobe: 5-7 Versatile Pieces
Pick 3 tops in neutral colors that mix and match with every bottom
Black, navy, gray, and olive work with everything. One quick-dry synthetic top for active days, one merino wool top that resists odor for 3-4 wears, and one presentable button-down or blouse covers casual, active, and semi-formal situations.
Choose fabrics that dry overnight when hand-washed
Avoid cotton — it holds moisture, takes 12+ hours to dry, and wrinkles easily
Pack 2 bottoms: one pair of versatile pants and one pair of shorts or a skirt
Synthetic travel pants in dark colors hide stains and dry in 4-6 hours. A single pair worn 5 times between washes weighs 300g versus packing 5 pairs of jeans at 4kg total.
Bring 1 lightweight layer that doubles as warmth and rain protection
A packable down jacket compresses to the size of a water bottle and weighs 250-400g. Pair it with a $20 ultralight rain shell (100-150g) that packs into its own pocket for full weather coverage under 550g.
Limit footwear to 2 pairs: one walking shoe and one sandal or flip-flop
Shoes are the heaviest items in any bag. Wear the bulkier pair during transit. Trail runners work for hiking, city walking, and casual dining. Sandals cover beaches, hostels, and warm-weather evenings.
Pack 3 sets of underwear and socks in quick-dry material
Merino wool or synthetic underwear dries in 2-4 hours and resists odor for 2 days. Three pairs create a rotation: one wearing, one drying, one clean. This replaces packing 7-10 pairs for a week.
Packing Cubes Strategy
Use 3-4 packing cubes to compartmentalize clothing by type
One cube for tops, one for bottoms and layers, one for underwear and socks. Compression cubes squeeze out 30-40% of air volume, turning a stuffed bag into one with room to spare.
Assign one cube as the "dirty laundry" cube that expands as the trip goes on
Use different colored cubes so you can find items without unpacking everything
Place heavy items (shoes, jeans) at the bottom of the bag near the wheels or back panel
Weight distribution matters for both comfort and rolling stability. Heavy items at the bottom keep a backpack balanced and prevent a rolling bag from tipping. Shoes go in first, wrapped in a shower cap or bag.
Keep a small pouch with in-flight essentials accessible at the top of your bag
Include headphones, a phone charger, eye mask, earplugs, a snack, and any medication. Digging through a packed bag mid-flight wastes time and disturbs your neighbors. A flat pouch under 500g handles this.
Toiletry Minimization
Switch to solid toiletries: shampoo bar, soap bar, solid deodorant
Solid bars last 50-80 washes (2-3 months of travel), weigh 40-60g each, and are exempt from the 100ml liquid rule. A shampoo bar, soap bar, and solid deodorant replace 3 bottles and save 400-600g.
Pack solids in a ventilated tin or mesh bag so they dry between uses
Bring a small container of sunscreen — this is the one liquid worth keeping
Use a single clear quart-sized bag for any remaining liquids (100ml max each)
The TSA/EU liquid rule allows one 1-quart bag per person. Fit contact solution, sunscreen, and toothpaste in this bag. Transfer products into reusable silicone tubes ($8-$12 for a set of 4) instead of carrying full-size bottles.
Bring a microfiber towel instead of relying on accommodation towels
A 60x120cm microfiber travel towel absorbs 4 times its weight in water, dries in 2 hours, and weighs 150-250g. It replaces the need for beach towels, gym towels, and backup towels in budget accommodation.
Pack a pill organizer with just enough medication and vitamins for the trip
A 7-day pill case weighs 30g versus bringing full bottles at 100-200g each. Pre-sort daily doses before departure. For prescription medications, keep them in original bottles in your carry-on for customs verification.
Tech Essentials Only
Limit electronics to phone, one charger with multiple cable types, and earbuds
A single 65W GaN charger ($25-$40) powers a phone, tablet, and laptop from one outlet. It weighs 100-150g versus carrying 3 separate chargers at 400-600g total. Add a 1m USB-C cable and a short Lightning or USB-A adapter.
Download maps, entertainment, and translation packs offline before departure
Bring a universal plug adapter if traveling to a different outlet standard
Decide whether a tablet or e-reader is worth the weight for your trip length
An e-reader weighs 175-200g and holds thousands of books with 6 weeks of battery life. A tablet weighs 400-600g but replaces both the e-reader and a laptop for light tasks. For trips under 5 days, your phone handles both roles.
Skip the camera if your phone has a capable camera — it saves 500g-1kg
Modern phone cameras produce 12-50 megapixel photos that are indistinguishable from dedicated cameras for social media and prints up to 8x10 inches. A dedicated camera only justifies its weight for professional photography or extreme zoom needs.
Laundry Planning
Pack a 30ml bottle of concentrated laundry soap or 3-4 laundry sheets
Laundry sheets weigh 2g each, dissolve in water, and wash a full sink load per sheet. They pack flat in a pocket of your bag and eliminate the need for a liquid soap bottle entirely.
Bring 2-3 meters of braided clothesline with built-in clips
A twist-and-clip clothesline weighs 50g and stretches between any two anchor points — shower rod, door handle, balcony rail. Hang-drying 2-3 items overnight means you never run out of clean clothes.
Plan a laundry day every 3-4 days for trips longer than 5 days
Laundromats cost $3-$8 per load worldwide. Hand-washing in the sink is free and takes 15 minutes for 3-4 items. Schedule laundry on a rest day or rainy afternoon when you would be indoors anyway.
Learn the sink-wash technique: soak, agitate, rinse, roll in towel, hang
Fill the sink, add soap, submerge clothes for 10 minutes, agitate for 2 minutes, rinse twice. Roll each item tightly in your microfiber towel to extract 70-80% of water, then hang. Most synthetics dry fully in 4-8 hours.
Bag Selection and Weight Management
Choose a carry-on bag that fits airline size limits: 55x40x20cm (22x14x9 inches)
Most international airlines allow carry-ons up to 55x40x20cm and 7-10kg. Budget airlines are stricter — some limit to 40x30x20cm for free and charge $30-$60 for larger cabin bags. Check your airline before buying a bag.
Measure your bag with contents to confirm it fits in the sizer at the gate
Choose a bag that opens fully flat (clamshell) for easy packing and access
Weigh your fully packed bag on a luggage scale before leaving home
A digital luggage scale costs $8-$15 and saves you $30-$80 in overweight fees per flight. Weigh once packed and remove items until you are 0.5-1kg under the limit to account for souvenirs and snacks added during the trip.
This formula fits in a 35-45 liter bag and covers 2 weeks of travel with laundry. For warm destinations, swap 2 bottoms for 2 shorts. For cold destinations, replace 1 top with a thermal base layer.
Leave 10-15% of your bag empty for purchases, souvenirs, or unexpected needs
A bag packed to 100% capacity on day one has no room for a bottle of wine, a market find, or an extra layer bought at the destination. Starting at 85-90% full gives you flexibility without an extra bag.
Frequently Asked Questions
What size backpack do I need for one-bag travel?
A 35-45 liter pack fits most airline carry-on dimensions (55x40x20 cm) and holds 5-7 days of clothing plus toiletries. Bags above 45 liters typically exceed carry-on limits and must be checked. Clamshell-opening packs (like a suitcase) provide easier access than top-loading designs when living out of the bag daily.
How do I pack light for a two-week trip?
Apply the 5-4-3-2-1 rule: 5 tops, 4 bottoms, 3 pairs of socks and underwear, 2 pairs of shoes, 1 hat. Merino wool and synthetic fabrics dry overnight after hand-washing in a hotel sink. Roll clothes instead of folding to eliminate air pockets and reduce wrinkles. Packing cubes compress clothing and keep the bag organized.
Should I bring a travel towel?
Microfiber travel towels weigh 200-300 grams, dry in 2 hours, and pack to the size of a paperback book. Hotels and Airbnbs provide towels, but hostels, beaches, and overnight trains often do not. A full-size bath towel weighs 500-700 grams and takes 8-12 hours to dry so the weight and space penalty is not worth it.
Can I do laundry while traveling?
Laundromats exist in most cities worldwide and cost $3-8 per load. Hand-washing in a sink with travel detergent sheets handles underwear, socks, and light tops overnight. Pack a 3-foot length of braided clothesline that stretches between shower rods, door handles, or balcony rails for drying without clips.
What toiletries can I skip packing?
Hotels, hostels, and Airbnbs in virtually every country provide shampoo and soap. Solid alternatives like shampoo bars and toothpaste tablets eliminate liquid restrictions entirely for carry-on travel. Deodorant and sunscreen are the two items hardest to find in preferred brands abroad so pack those from home.
