Best Large Backpacks
Osprey Atmos AG65
Travelling or trekking for the whole day takes it toll, especially when you’re laden down with gear. Which is why our top pick is designed to take the load off. It’s designed around smart anti-gravity suspension tech that spreads the load across your body, so you feel like you’re carrying far less than you actually are.
Minimalist but stylish, the Atmos AG65 is built around an adjustable harness and hip belt that helps the pack wrap around your body, hugging to your contours so it doesn’t bounce around.
There’s massive amounts of storage, with front stretch mesh pockets to store quick access gear like rain-proofs, web attachment points, a hydration sleeve that holds up to a 3 liter reservoir, sleeping bag straps, a trekking pole attachment, basically anything you might need.
Made from highly ventilated, incredibly comfortable material, it comes in 3 sizes that can be fit to you, with the medium size holding up to 50lbs of gear. Just use Osprey’s own bespoke sizing chart to find out what fit you need.
If you want the best large hiking backpack on the market, that’s going to take every situation in its stride, in our opinion there is no better choice.
Tortuga Men’s Setout
Designed to be the biggest bag you can possibly take as a piece of carry on, the advantages of the Setout are obvious.
To start, it’s a 45 liter backpack, sized specifically to be exactly as large as airline regulations allow. Construction is flawless, with 900D polyester that’s treated to be weather resistant, injection moulded foam in areas that take increased pressure, heavy duty shoulder straps, and a removable hip belt that takes as much as 90% of the weight off your shoulders.
Whether you’re going on a weekend break or touring around the world, this bag is going to take everything in its stride, and stay comfortable the whole time.
Internal storage is huge, taking a full sized laptop and a week’s worth of clothes easily, with a full YKK zipper that runs the entire length of the bag and lets it open fully like a suitcase, for instant access.
Internal storage is neatly divided, with the extra option for storage cubes, and if you don’t need a full size 45 liter backpack, there is a smaller option available.
Teton Grand 5500
An absolute monster, the Teton Grand is one of the largest bags we’ve looked at, and has enough carrying capacity for a week long expedition into the toughest jungle, or a few days away with the family.
Holding a massive 90 liters of internal space, the Grand 5500 is colossal, but still only weighs a really reasonable 2.7kg (6lbs.) Built around a solid aluminum internal frame, the pack will keep its structure no matter what it’s holding. Storage pockets are scattered around the pack, including a sleeping bag pocket and 3 liter detachable daybag.
Despite the size, it’s incredibly comfortable, even when loaded down. Wide shoulder straps and a big waist belt spread the load across your body, all of which has multiple points of adjustment to fit to almost all body types.
The whole thing is also covered by Teton’s lifetime warranty. Whether you’re taking this to the top of a mountain or a woodland walk, the Teton Grand 5500 is going to take it all in stride.

Built around the needs of transporting modern technology, Veckuson’s gaming backpack is an absolute monster, if you need to transport half an office or a gaming rig to an event.
The 55 liter capacity can hold 2 large laptops (up to 18.4 inches) and a tablet in padded, secure internal storage. There’s a phone pocket with phone connection, and a headphone port so you can listen and talk on the go. Built in USB charging lets you connect a power bank and keep everything up and running. There’s also a secure RFID protection pocket to keep your wallet, credit cards and data safe.
Water resistant in case of sudden showers, the whole bag is made from high-quality polyester and breathable mesh. Adjustable shoulder straps hold it securely to your body, and when you get to the airport, the whole thing opens to a completely flat 180 degrees.
One thing to bear in mind is that this bag is a little too large for a carry-on piece when it’s fully packed, so be careful if you’re flying. But apart from that, this is the best way to transport your tech on your back.
Swissgear 1900 Scansmart
Equally at home on business trips or accompanying students on bohemian backpacking trips, the Swissgear 1900 is a stylish and effective piece of luggage.

Best large backpack buying guide
Most standard backpacks and day bags sit somewhere in the 20 to 35 liter range. A large backpack, whether you’re using it for a long hike, a weekend break, or something else entirely, is generally going to be anything upwards of 40 liters.
The largest backpacks can run upwards of 80 or 90 liters, and are suitable for multiple day hikes, including tents and gear. But beware that backpacks over around 45 liters are going to be much harder to travel with when you’re not walking. You’re likely to face checked baggage fees when you fly, and might need to stow your luggage on trains and buses.
Increased size comes with increased weight, but better quality backpacks will be made of materials and use manufacturing methods that help reduce the total weight you feel.
Things like adjustable handles,
Straps and carry handles
Obviously, a big backpack packed full holds a lot of weight, and after a long day, you’ll definitely start to feel the strain.
Bigger backpacks tend to have straps designed to shift the load. Smaller, conventional backpacks put all of the weight on your shoulders. But properly designed travel packs will have hip straps that shift the majority of the weight downwards.
More expensive and larger backpacks may even have full hip belts that take almost all of the weight and put it on your hips instead of your spine.
When it comes to shoulder straps, bigger tends to be better. Thicker and wider straps will distribute the weight better, but be warned, don’t buy straps that are too big if you’re a smaller person, as you’ll get swamped.
Finally, there are going to be times when you’re not carrying your backpack on your back. A lot of packs have carry handles, most commonly on the top, but larger packs might also have side mounted carry handles, or even wheels, allowing you to carry them like a piece of hard sided luggage.
Most modern backpacks are made out of the same two or three materials, namely nylon, cordura and polyester.
Polyester is the cheapest and lightest material. It’s generally not suitable for larger backpacks, as it’s vulnerable to ripping and tearing, especially if overstretched.
Cordura is an incredibly durable, fully synthetic material that’s used in a wide variety of other applications, including hiking clothes and military gear. The strength is balanced out by added weight and cost.
Nylon is a happy medium between polyester and cordura, being reasonably costed for good performance. Cheaper backpacks might still rip and tear easily, so look for reinforced nylon material, commonly called nylon-6 or rip-stop nylon.
Half of the struggle when you’re packing is organization, and a good backpack will have multiple pockets to give you as many options as possible.
Look for bags with a large number of external pockets, which are ideal for quick access to things you need regularly, for example water and documents, and secure internal pockets, which can be used to store things like identification and money.
Font Loading vs Top Loading
If you need ready access to your gear, you should look for a front loading backpack.
The difference is right there in the name. A top-loading pack is only accessible from the top, which is fine on smaller backpacks, but on a fully laden large pack, means the items at the bottom are basically inaccessible.
A front-loading pack, on the other hand, can zip down much further, giving you much easier access to everything inside the pack. Given the choice, front-loading is always preferable.
If you’re travelling at all, you’re going to need to make sure that your bag has paired, lockable zippers that accept a padlock, so you can keep your things safe and secure.
It’s also worth pointing out here that when you’re buying a padlock to fit your bag, you should buy locks that are marked as TSA safe. This lets your bag be opened so it can be checked without breaking your locks. TSA safe padlocks should be available at all major retailers, on and offline.
What size backpack do I need?
The size of your backpack depends on what it’s going to be used for.
Consider the amount of space you’re going to need. The best way is to use a sizing guide, like this one, to approximate what you’re packing inside.
Then consider any specialist needs you might have, including:
- What weather conditions you’re likely to face
- Whether you regularly travel by air
- What you’re storing inside, for example, tech like a laptop
- How comfortable it’s going to be on long hikes
- Whether you need a liquid bladder pocket
How large can my backpack be for carry on luggage?
The most common dimensions for carry on luggage in the USA is 22 x 14 x 9 inches. That works out at around 45 liters.
Some carriers might be different, so it’s always worth double checking with your particular airline what the specifications are. But 45l is a safe limit to play around.
