3 Best Backpack and Travel Picks in 2026

A backpack built for travel needs to do three things: fit an airline's cabin-bag sizer, carry comfortably on foot for a full day, and pack down small enough for a train's overhead rack. Below are three real, verified picks that do all three.

Plenty of travel backpacks are built with US flights in mind. They are fine for a domestic carry-on but too deep for Ryanair or easyJet's cabin-bag sizers. If a budget carrier is part of your trip, size comes first, not brand or looks.

#1. Osprey Farpoint 40: most padded carry for a long walking day

Osprey Farpoint 40 Travel Pack

Our verdict:

Most padded carry for a long walking day

Best for travelers who want a padded hip belt and load-lifter straps for full days on foot.

View on Amazon

• Stowaway harness and hip belt for check-in or travel days
• Zippered 16-inch laptop and tablet sleeve
• External zip pocket for toiletries
• Sized as a domestic carry-on

Keep in mind: at about 23 cm deep it runs over Ryanair's depth limits on both tiers.

Product details checked September 2026

The Farpoint 40 weighs about 3.5 lb (1.6 kg) and measures roughly 21.7 x 13.8 x 9.1 in, about 55 x 35 x 23 cm. It is a clamshell-opening pack with a padded hip belt, load-lifter straps, and a quick-access sleeve for a 16-inch laptop.

It fits easyJet's large cabin bag comfortably. On Ryanair, plan to check it or pay for the Priority add-on. The hip belt and load lifters carry weight well on cobblestones, which matters more than a lighter pack once you are a few hours into a walking day.

#2. Nomatic Travel Bag 40L: best pack that converts to a duffel

Nomatic Travel Bag 40L

Our verdict:

Best pack that converts to a duffel

Best for trips that run longer than a single work week and might add a rest day.

View on Amazon

• Built for trips of about 3 to 7 days
• Fits up to a 16-inch laptop and tablet
• Converts between a backpack and a duffel
• Carry-on size with a luggage pass-through

Keep in mind: its 23 cm depth still runs a little over Ryanair's tighter allowances.

The Nomatic Travel Bag 40L weighs about 3.42 lb and measures 21 x 14 x 9 in, roughly 53 x 36 x 23 cm. It converts from a backpack to a duffel, useful if your back needs a break between train stations.

It fits easyJet's large cabin bag well. It carries a laptop and tablet up to 16 inches, has a dedicated shoe compartment, and includes a luggage pass-through strap plus a set of waist straps you can remove once you are off the plane.

#3. Peak Design Travel Backpack 45L: best pack for a trip that grows

Peak Design Travel Backpack 45L

Our verdict:

Best pack for a trip that grows

Best for travelers who want one bag that shrinks for the flight and grows once they land.

View on Amazon

• Expands from a 35L profile to 45L
• Weatherproof 400D recycled nylon shell
• Top, side, and rear access points
• Tuck-away shoulder straps, hip belt, and a luggage pass-through

Keep in mind: expanded to 45L it is too big for any of the cabin allowances above.

Product details checked September 2026

The Peak Design Travel Backpack compresses to a 35L, 56 x 33 x 24 cm profile, or expands to 45L at 56 x 33 x 29 cm. It weighs 4.5 lb (2.05 kg) with a padded 16-inch laptop sleeve.

Compressed, it fits within easyJet's large cabin bag dimensions, though its 56 cm length sits right at that ceiling. This is the pick for travelers who want one bag that stays small through airport security, then grows once they are on the ground picking up extra layers or souvenirs.

Factors to consider when matching a backpack and travel plans

Front-to-back size first

Most standard 40L backpacks run 22 to 24 cm deep. That crowds easyJet's large cabin bag limit and usually runs over Ryanair's tighter allowances. Look at the third number in a pack's listed dimensions before anything else.

Weight of the empty pack

A 40L pack that weighs close to 5 lb empty leaves less room under a 10 kg cabin-bag weight limit once it is packed. A 3 to 3.5 lb empty pack gives you more to work with.

How it carries loaded

A hip belt and sternum strap matter more on cobblestones than on flat sidewalks. Uneven stone streets shift weight around, and a pack with only shoulder straps wears on you by hour three of a walking day.

How it fits into a train rack

European train overhead racks are narrower than a lot of US train and plane bins. A pack with compression straps that cinch the load down packs into that space more easily than one that stays fully expanded.

How we picked these backpack and travel matches

Every fact above comes from the brand's own product page or the Amazon listing we link to. We left out prices and star ratings on purpose, since they shift often and a stale number does not help you plan a trip.

Matching pack size to trip length

A trip of about a week fits comfortably in any of these three packs on their standard setting. For a trip closer to two or three weeks, the Nomatic's duffel conversion or the Peak Design's expanded 45L setting gives you the extra room without switching to a second bag.

Bottom line

If your trip is mostly budget-carrier flights inside Europe, expect to check or pay extra for any of these three on Ryanair, since all run deeper than its tightest allowance. If you are flying carriers with more generous carry-on rules, or checking a bag on at least one leg, the Farpoint 40, Nomatic 40L, or Peak Design 45L each give you real room to work with, just in different shapes.

Questions people also ask

What's the difference between a personal item and a cabin bag on Ryanair?

The free personal item is smaller, at 40 x 30 x 20 cm, and goes under the seat. The paid Priority cabin bag is bigger, at 55 x 40 x 20 cm, up to 10 kg, and goes in the overhead locker.

Does an empty pack's weight matter?

Yes. A heavier empty pack leaves less room under a strict cabin-bag weight limit once it is packed. A pack around 3 to 3.5 lb empty gives you more to work with than a heavier one.

Do I need a hip belt for a short city trip?

A hip belt matters most on cobblestones and long walking days. For a trip that is mostly flat sidewalks and short walks, shoulder straps alone can be enough.
