Why choose a 40L backpack for travelling
- Allows you to travel carry on only – A 40L backpack is about the perfect size for fitting within most airlines’ carry on luggage requirements, even those strict budget airlines in Europe. Traveling with only carry on luggage reduces airline luggage fees and helps you get out of the airport faster. It also reduces the temptation to over pack for a trip.
- Holds a comfortable amount to carry – 40 liters is roughly 10.5 gallons for all of us who aren’t able to imagine metric accurately. It might sound like a lot to carry, but my 40L backpack weighs about 12 kgs or 26 lbs when absolutely stuffed to the brim, including a laptop. Most people can comfortably carry around that amount of weight in a good back that sits well and has straps that distrubute the weight evenly across the torso.
What to look for in a 40L travel backpack
To find the best 40 litre backpack for your next trip you need to consider a couple of key features before you make your purchase.
- Choose a travel-specific backpack, not a hiking backpack – This is absolutely key for travelers. The best 40L rucksack for travel is one that doesn’t stuff from the top, rather opens up clam-shell style so you can get a good look at the contents of your bag at each stop you make.
- Lightweight – The lighter you backpack the easier it is to carry. Plus you can pack more in before you hit airline weight restrictions for carry on luggage. Remember that while weight of your carry on bag isn’t restricted in the US, it almost always is abroad. For example, in New Zealand & Australia you can only carry on 7kgs or 15lbs. On budget airlines in Europe like RyanAir and WOW, you’re generally allowed up to 10kgs or 22lbs of carry on luggage. You do need to check each airline’s requirements individually before you travel but, the lighter the backpack you buy, the easier this becomes to meet. My Kelty Redwing weighs about 12kgs if it absolutely stuffed full!
- Unisex vs Womens – If you’re a man, the choice is simple, go for the unisex option when choosing a 40L backpack for travelling. If you’re a woman, you need to look at whether you need a backpack specifically designed for women or if a unisex one will work for you. If you have a small frame or a particularly short (like me!) then a backpack specific to women is probably best for you.
- Good straps – The straps can make or break a backpack (and your back!) when traveling. Looks for a backpack that has adjustable shoulder straps, a hip belt and a chest strap. This allows the weight of your backpack to be distributed evenly across your torso which minimizes discomfort to your shoulders and back. Also look at the “grab” handles on the bag that allow you to pick it up easily when loading into an overhead compartment or into the trunk of a taxi. They grab handles should be strong and padded for comfort.
- Laptop storage and access – Good laptop storage is important if you’re traveling with technology. A padded iPad sleeve also helps protect your devices. One of the biggest hassles when traveling is taking your laptop out at airport security so having a backpack that allows you to easily pull it out and put it back without everyone seeing your underwear or dirty laundry is a huge bonus.

Our pick for best 40 liter backpack for women!
I love my Kelty Redwing 40L backpack! As a short woman (I’m 5’2″) I definitely need to go for a backpack specifically designed for women as I’m shorter through the torso. The Kelty Redwing 40 fits me perfectly. It has fully adjustable external suspension which is so helpful if you have a smaller frame as you can get the backpack fitted correctly and not feel swamped. Although we’re talking about 40L carry on backpacks here so you’re not going to be too overwhelmed by any of them if you’re an average height woman.
- Comes in two colors – turquoise or black
- Suspension frame that adjusts to your torso
- Shoulder straps, chest strap & waist belt to distribute the load across your whole torso for comfort
- Ventilated back panel to keep your back cool
- Laptop sleeve inside the main compartment
- External stash pocket on the front of the backpack for a hoodie, jacket or travel pillow

If you’re looking for a secure bag that can’t be slashed or tampered with then this is an excellent choice.

Our pick for best 40L travel backpack on a budget!

- Comes in nine colors so great if you’re kitting out a family in different colored packs but want everyone to have the same style
- Mesh lined shoulder straps for comfort, chest strap but no hip belt
- Shoulder straps unclip and can be stowed away
- External laptop compartment at front of bag
- External compression straps reduce the profile of the bag
Our pick for best carry on bag for taller people!
OK this one is slightly over the 40L mark but it’s so well-designed, and so many people I know rave about it, that I had to include it in my list of best carry on backpacks for travel. A group of travelers came together to design this pack with urban travelers in mind. None of its features are too flashy but they all meet the average travelers needs. The straps stow away, the two handles are nicely padded for extensive carrying and the front loading design allows quick access to belongings.
- Padded hip belt for a more comfortable carry
- External laptop pocket at back of the bag
- Lockable zippers
- Fixed shoulder and hip straps meaning this backpack is suitable for people with a 18-22″ long torso (great for taller people!)
- Padded mesh back to prevent sweating
- Straps zip away for protection and style when you don’t want to look like a backpacker
- 44L so slightly over the 40L mark but still within the carry on requirements for airlines
Quick Tips for Traveling with Carry On Only
- Create a travel caspule wardrobe by choosing items that all mix and match with each other.
- Pack layers rather than bulky items.
- Pack a week’s worth of clothes and do laundry on the go either by handwashing or using a hotel/Airbnb laundry room.
- Roll your clothes to save space.
- Use packing cubes to organize and compress your clothing. You can read my guide to packing the right packing cubes and how to use them here.
- Don’t pack items just because you “might” need them e.g. umbrellas or evening wear. It’s better to buy them on the road when you do need them than to pack things that aren’t necessary.
- Simplify your travel toiletries. For a full list on what toiletries to pack read this post.
