Check priceWhat to pack for a backpacking hostel trip
One carry-on pack, a liner for the bunk, and a stash for the passport that stays on you.
A backpacking hostel trip is the solo carry-on journey. The bag has to clear a gate and still walk from the station to a locker. The liner is for the sheet you do not control. The passport stays on your body, and a tag stays on the bag you would hate to replace.
The picks below are gear already filed on the A solo flight, carry-on only journey. Each line says why we picked it for this trip.
Stay in the 35 L Aer and run laundry once. The week-long list is built for that.

Eagle Creek
Eagle Creek Pack-It Reveal Cube
Why we picked it A hostel room is a bad place to dump the whole bag. Clear cubes show a clean shirt without a full unpack.

Trtl
Trtl Pillow
Why we picked it Overnight buses and the flight in. Trtl's wrap packs smaller than a U-pillow, which matters in a 35 L bag.

Columbia
Columbia Men's Watertight II Rain Jacket
Why we picked it The walk from the station is where the rain starts. A packable Omni-Tech shell with its own pocket is the layer, not a second coat bag.

Check priceThe checklist above is the hostel carry-on. The solo backpacker journey guides also cover walking, rail, a cruise, and a road trip.
Also on the list
The things this trip forgets when the bag is already full.
- A lock you already trust. The AirTag does not lock a locker.
- Shower shoes you already own. They are not a gear pick here.
- If the week is buses and no flight, the solo on-foot journey uses the Farpoint 40 instead of the Aer.
- One laundry stop. The week list is built for a wash, not for 14 shirts.
FAQ
What is the one bag for hostels and flights?
The Aer Travel Pack 4, 35 L. Aer lists 21.5 x 13.5 x 9 in and 3.90 lb. If you are not flying, the Osprey Farpoint 40 is the walking bag on the solo on-foot journey.
What helps a hostel bunk?
A silk liner. Sea to Summit lists the Traveller at about 6 oz with a pillow slip. It does not replace a sleep system you already use for camping.
Where should the passport go in a shared room?
In the RFID neck stash, on you. A copy can stay in the locker bag. The original should not.
