A traveler who started a Southeast Asia trip with 30kg of checked luggage is now desperately trying to downsize to carry-on only after dealing with back pain and massive baggage fees. The question resonates with anyone who's dragged an oversized backpack up hostel stairs: is long-term travel with just 7-10kg actually realistic?
"My back hurts as hell!!" wrote the traveler on r/solotravel, seeking advice from experienced nomads who've mastered the art of traveling light. The post sparked responses from the r/onebag community — travelers who've perfected the minimalist approach to extended travel.
The math behind carry-on travel
Most airlines allow carry-on bags around 7-10kg (15-22 lbs), with dimensions typically 55cm x 40cm x 20cm. Popular bags in this category include the Osprey Farpoint 40, Tortuga Setout, and various Peak Design offerings.
The real constraint isn't volume — it's weight. A 40-liter backpack can physically hold far more than 10kg, which forces ruthless prioritization. Every item must justify its weight and volume against the frequency of use.
What experienced travelers actually pack
Conversations across r/onebag and travel forums reveal a consistent minimalist approach:
Clothing — 5-7 days of clothes maximum, with everything quick-drying and suitable for layering. The standard formula: 3-4 shirts, 2 pants/shorts, 1 week underwear and socks, 1 fleece or light jacket, plus whatever you're wearing on the plane. Merino wool base layers get constant praise for being odor-resistant and packable.
Laundry strategy — Sink washing every 3-4 days, using quick-dry fabrics that go from wet to wearable in 6-8 hours. Pack a small amount of concentrated laundry detergent or travel-sized packets. Many travelers report that once you establish a laundry routine, carrying more clothes feels unnecessary.
Footwear — Maximum two pairs: one everyday shoe (trainers or walking shoes) and one secondary option (sandals or minimalist shoes). Shoes are the heaviest items in most bags, so choosing versatile options matters.
Tech — Laptop if needed for work, phone, chargers, and one international adapter. Everything else is optional. Many travelers skip cameras entirely, relying on smartphone photography.
