The Tortuga Outbreaker Backpack is our pick for the best carry-on backpack. It’s the maximum carry-on size with plenty of space and great organisation, and it’s comfortable to carry.
In this Tortuga Outbreaker review, we share the good and bad of the Outbreaker after a year of travelling full-time with it.
We also compare it to the new Tortuga Travel Backpack (an updated version of the Outbreaker).

Tortuga Travel Backpack Review (New)
In January 2023, Tortuga released the new Tortuga Travel Backpack. This is an updated version of the Outbreaker with some significant changes.
It comes in 40L and 30L versions, both of which are slightly smaller than the Outbreaker.

Tortuga Travel Backpack vs Tortuga Outbreaker
Here’s how the new Tortuga Travel Backpack compares to the Tortuga Outbreaker:
- Smaller – The new backpack is slightly smaller at 40L vs 45L. This is so that the bag meets the carry on requirements for international airlines as well as domestic US ones.
- Lighter – It’s 10% lighter at 2kg vs 2.3kg.
- Rounder corners – The new backpack shape is softer and less boxy.
- Recycled fabric – The new fabric is still waterproof, but it’s 100% recycled and is lighter weight and even more durable.
- Improved suspension system – Like the Outbreaker, you can adjust the suspension system for your height. In the new backpack, this is easier to do.
- Fewer pockets – To reduce weight, the new design is simpler with fewer pockets. There’s still plenty of organisation, though.
Everything else stays the same.
Overall, I think these are all positive changes. Check out the Tortuga Travel Backpack here.

This review is of the Outbreaker Travel Backpack 45L (there’s also a 35L version).
Tortuga Outbreaker Backpack Pros
Tortuga was created by travellers for travellers. Fred and Jeremy created the original Tortuga backpack after being disappointed with traditional hiking backpacks while travelling around Europe.
They set out to create their perfect backpack and have since grown into a company that truly understands the needs of urban travellers.
Simon travelled with a Tortuga travel bag for six years—they make the best backpacks that are both practical and stylish.
The Outbreaker is one of the few backpacks we’ve found that meets all of our requirements for long term and digital nomad travel.
The Outbreaker 45L is the maximum carry-on size that most airlines allow.
The rectangular design maximises the amount you can take on a plane and makes it easy to pack, especially if you use packing cubes like us.
It’s very spacious and easily fits all of Simon’s stuff including his extensive electronics collection.
Simon took the Outbreaker on 14 flights in Europe, Africa, and Asia including budget airlines EasyJet and AirAsia. His previous Tortuga V2 came on countless flights in 14 countries including Ryanair.
The Outbreaker is made from 4-layer, waterproof sailcloth that won’t scuff or tear and is very durable. It’s highly water-resistant so you don’t need a separate rain cover.
The Outbreaker is a step up from the quality of the Tortuga V2, which we were already impressed with. Simon used his previous Tortuga for full-time travel for over two years and it barely showed any signs of wear and tear.
After a year of use, the Outbreaker still looked like new—we’d expect it to last for many years.
Padded hip belt
A padded hip belt is the most difficult feature to find in a carry-on backpack, but we think it’s the most important.
The hip belt transfers the bag’s weight onto your hips and prevents back and shoulder pain. This is especially important if you travel with a lot of heavy electronics like we do.
The Outbreaker has a very robust hip belt, which combined with the suspension system and padded shoulder straps, makes it very comfortable to carry even when Simon’s backpack weighs 12 kg (26 lbs).
Although the Outbreaker is relatively heavy, it doesn’t feel like a burden on his back.
The Outbreaker has a height adjustment system, which allows you to adjust the torso height and find your perfect fit.
This means it fits a wide range of people, even those with smaller torsos.
Front-loading like a suitcase
Unlike traditional hiking backpacks that open from the top and make it hard to access your stuff, the Outbreaker opens along the entire front, like a suitcase. It’s much easier to pack and keep things organised.
The fleece-lined laptop compartment is located at the back of the Outbreaker, close to your body for the best weight distribution.
It fits laptops up to 17-inches and there’s enough padding that you could probably even skip a case.
Simon packs his 15-inch MacBook Pro in a neoprene case first for extra protection and there’s plenty of space for it.
In front of the laptop sleeve, there’s a tablet sleeve where Simon stores his 12-inch iPad Pro.
The Outbreaker’s entire electronics compartment can be unzipped and laid flat on the conveyor belt at airport security.
Apparently, this is approved by the TSA so that you don’t need to remove your laptop from the backpack. I’m not sure if this works in practice, as on the flights we’ve taken with the Outbreaker they were often strict about removing your laptop, sometimes even from its sleeve.
The backpack has a ton of pockets to organise all your stuff. As Simon prefers using packing cubes, he doesn’t use most of them, but they lie flat if you don’t need them.
There are three sections in the Outbreaker, each accessed by a different zip at the top of the bag. This is a little confusing until you learn which section is which.
The front section unzips halfway and is designed for easy access to small items in transit.
There’s a mesh pocket in the front, a zippered pocket at the back, and an organiser panel with small pockets for items like your passport (although we always carry ours on our person), pens, cards, sunglasses, etc.
Behind that, there’s a fleece-lined section for an e-reader. There’s also a clip for keys.
The middle main section is the largest and unzips on three sides so it’s really easy to pack.
There’s plenty of space for Simon’s large clothes packing cube, electronics cube, shoes, toiletry case, travel towel, and AeroPress coffee maker.
There are a number of pockets in the main section—four small pockets around the edges (Simon uses one for his hard sunglasses case and another for his AeroPress) and two mesh compartments on the opposite side (useful for dirty laundry or small items).
If you don’t need them, they can be flattened so they don’t take up space.
The electronics compartment is at the back and lies completely flat. It fits a laptop and tablet in separate sleeves (as described above).
Opposite there are three mesh pockets for accessories like chargers, adapters, cables, etc. (Simon prefers to use an electronics cube in the large main compartment instead).
There are also a number of pockets on the exterior of the backpack. On the front, there are two zippered pockets.
The two stretch pockets on the sides fit a water bottle or umbrella.
The small pockets on the hip belt are designed to conveniently stash coins and keys when going through airport security. Simon doesn’t use these pockets much other than for tissue in the front pocket.
We love that the Outbreaker has a simple, sleek, black design so it doesn’t stand out too much.
We like to lock our backpacks with a small combination lock to prevent opportunistic theft. All three compartments of the Outbreaker are lockable.
You do need two locks to fully secure the backpack. The two front compartments are close enough together to share a lock (or Simon keeps the front compartment unlocked for easy access) and you’ll need a second lock for the electronics compartment at the back. Or you could choose just to lock your electronics compartment.
35L version available
The 45L Outbreaker is ideal if you want to pack the maximum possible in your carry-on, but it’s too big for some people, so I’m pleased that Tortuga now offers the Outbreaker in a smaller 35L size.
The 35L has all the same features of the 45L but is smaller (20.3 x 12.9 x 8.2 inches), lighter (4.5 lbs / 2kg), and cheaper ($299).
Tortuga offers free US shipping and if the backpack doesn’t work out for you after a test pack, return it unused within 30 days for a full refund. They also pay for the return shipping on US orders.
Tortuga Outbreaker Backpack Cons
Update: The new Tortuga Travel Backpack is lighter than the Outbreaker.
The improved build quality and organisation of the Outbreaker means that it’s significantly heavier than the Tortuga V2 and Setout (neither of which are available any longer).
At 2.3 kg (5.1 lbs) the bag itself uses up a good chunk of your carry-on weight allowance, especially in places like Asia where allowances are a stingy 7 or 8 kg.
In practice, though, this hasn’t been a problem. In over a decade of travelling carry-on only our backpacks have only been weighed once, so we’ve managed to get away with them being overweight many times.
We’ve written more about how to manage carry on luggage weight and size restrictions.
Bangkok Air did weigh Simon’s Outbreaker on one of our two flights with them, but when he explained that it was full of electronics that couldn’t be checked, they let him take it on.
The 35L version of the Tortuga backpack is lighter if weight is a concern for you.
Larger than some airlines allow
Update: The new Tortuga Travel Backpack solves this problem with a smaller size that meets requirements for even strict budget airlines.
The Outbreaker is within most airlines’ allowed carry-on size, but it’s a few centimetres over the size allowed by some strict airlines such as Ryanair, which has a 55cm x 40cm x 20cm limit.
(Note: with Ryanair’s new baggage policy you’ll need to pay an extra fee to be allowed a large bag as a carry-on).
We have travelled on Ryanair multiple times with the Tortuga, though, and had no problems taking it on the plane.
We don’t find airlines to be that strict about size and weight if you are travelling with a backpack as it’s less visible than a rolling suitcase.
The Outbreaker costs $349, but your luggage is the most important item you travel with, so we think it’s worth the investment and it will last for many years.
No shipping outside the US
The Outbreaker is only available from the Tortuga website and they no longer ship internationally. Your best option is to use a freight forwarder.
Tortuga Outbreaker Alternatives
When we originally wrote this Tortuga backpack review, the Outbreaker was Simon’s top pick for a carry-on backpack. He then switched to the Tortuga Setout, a lighter, less full-featured backpack.
Unfortunately, Tortuga is no longer selling the Setout, so we now think the Outbreaker is the best travel backpack.
Osprey Farpoint 40
Although Simon loved the Outbreaker, I originally felt it was too big and heavy for my needs and travelled with the Osprey Farpoint 40 instead.
At 38 litres and 1.3 kg (2.87 lbs) it’s a lot smaller and lighter than the Outbreaker.
There’s less organisation and the laptop sleeve isn’t as large or well designed as in the Outbreaker, and it’s at the front of the bag.
This worked with my light MacBook Air, but for heavier laptops, it’s more comfortable to carry the laptop closest to your body.
The Osprey Farpoint 40 does have a hip belt and is comfortable to carry.
The Osprey Farpoint 40 is worth considering if you want a smaller, simpler, cheaper, and lighter backpack and you aren’t travelling with a lot of heavy electronics.
Many digital nomads and long-term travellers end up choosing between Tortuga’s backpacks and Minaal’s.
The Minaal 3.0 is a stylish carry-on backpack, but although it costs the same as the Outbreaker, it’s only 35 litres and you have to pay extra for a hip belt (which doesn’t look as comfortable as Tortuga’s).
The number of carry-on travel backpacks on the market is growing but most miss features that we consider necessary like hip straps, front-loading design, or lockable zippers.
Tortuga Outbreaker Backpack Summary
The Tortuga Outbreaker travel backpack is an extremely well-designed bag that’s ideal for anyone who wants to maximise the amount they can travel with carry-on only.
It looks great and is spacious, durable, comfortable, and has plenty of organisation including excellent protection for your laptop and tablet.
If you want a waterproof bag with lots of organisation and a robust and adjustable suspension system, then the Outbreaker is the best travel backpack for you.

Tortuga Outbreaker vs V2 Tortuga Backpack: What’s New?
If you have the old Tortuga Backpack V2 and are considering an upgrade, here’s what’s different.
The Outbreaker has solved a number of small issues we had with the Tortuga V2.
- The Outbreaker comes in two versions—45 litres, which is similar to V2, and 35 litres, which replaces the Tortuga Air. Both now have hip belts, which was my main complaint with the Air.
- The new adjustable hiking-style suspension system makes it even more comfortable to carry and means it should fit more people than the previous backpack did.
- The bulky side pockets have been removed giving it a sleeker look.
- Instead there are two discreet water bottle pockets on the side that lie flat when not being used.
- The fabric is water-resistant and very durable.
- It opens fully on three sides like a book making it even easier to access everything inside.
- There is an improved fleece-lined laptop and tablet sleeve. The electronics compartment unfolds to lie flat on the X-ray belt to avoid taking your laptop out when going through airport security.
- The external front pocket is slimmer and doesn’t bulge anymore.
- It’s heavier—the 45-litre backpack is 5.1 lbs (2.3 kg), which is 1.45 lbs (0.64 kg) heavier than V2.
- The backpack shoulder straps can’t be packed away (although the hip belt can be removed), but Simon never used this feature.
- No side handle to carry it suitcase style (although Simon rarely used this).

Disclosure: Tortuga sent Simon the Outbreaker backpack for review, but he wouldn’t have travelled with it for a year if he didn’t genuinely think it’s an excellent bag.
