The Thule Aion Travel Backpack 40L has been an incredible travel companion. This backpack has been everywhere with me — on planes, trains, buses, and all throughout Europe — and it has held up perfectly. After all the miles, packing, unpacking, and daily use, it still looks and performs like new. The 40L capacity is the perfect size for travel, giving me plenty of room for clothing, electronics, and essentials without feeling like I’m carrying a huge bag. The organization is excellent, with thoughtful compartments that make it easy to keep everything accessible and organized while on the go. The build quality is outstanding. The materials feel durable, the zippers are strong, and the design is clearly made for people who actually travel. It’s comfortable to carry, even when fully packed, and the sleek black style works just as well in airports as it does walking around a new city. After putting it through real-world travel, I can confidently say this backpack is built to last. If you’re looking for a reliable travel bag that can handle adventures near and far, the Thule Aion 40L is an excellent choice.

I have a few semi high end travel backpacks, I'm a one bag traveler, if some place I can't go without carrying only a backpack, I just don't go. I also never check my bags, if I can't carry it on a plane, I don't use it. So a high quality and high capacity backpack is very important to me. I'm not a backpacker, I don't walk around anywhere with my backpack. The only place I will be carrying one is at the airport, so even though comfort is important, it's not on the top of my list. The Thule 40l feels comfortable enough. It doesn't come with a hip strap, but I never use one anyway. It has a very roomy main compartment, comes with compression straps, a builtin detachable wet bag, a small builtin mesh toiletry zip compartment, and a full length zip compartment for additional organization. The laptop compartment is also very large, even with a laptop and a tablet, it still has room for stuff. Since I travel light, I only carry a 12 inch laptop, so I will be using the laptop compartment for clothing in compression cubes or other stuff. The front organizational pocket is only 1/2 way deep of the bag, wish it was larger so I can fit a light jacket along with miscellaneous stuff. The hidden pocket at the back is great for passport, wallet and quick access to travel documents. There is one external water bottle pocket on the right side, has no strap, but feels snug enough. I wouldn't flip the bag over, the water bottle could fall out. I saw people complaining about the waxed canvas, saying it looks dirty and scratched upon arrival. My bag arrived clean as whistle, not a single scratch on it. I tried scratching it a few times with my finger nails to see if it would leave a mark, it didn't, so I'm not too worried about it looking ugly or "full of character" after a few uses. Not sure if the material is really water resistant, not going to test it, don't plan on walking in the rain or dunking it in a puddle. My trips are usually 2-3 weeks long, I travel to many parts of the world with backpacks ranging in sizes from 35l to 45l. This bag is 40l, should be big enough to carry 10 days of light clothes and toiletries. Men's clothing is bulkier and heavier than women's, my wife packs light too, she can literally fit 2-3 weeks of light clothes in this 40l backpack. No, we never go anywhere cold, hate the cold. :). The bag is made in Vietnam, a bit disappointing, was hoping it'd be made in a Western country. However, the construction seems solid and durable, only time will tell if it will hold up. At $200 price point, it's better made or equivalent to some of the more expensive backpacks on the market, and exceeds bags in its same class, Peak Design 45l or Osprey Porter for example, both of which I also own. If you are also a one bag traveler, get the 40l version. If you carry a backpack in addition to check luggage, this bag might be too big, get the 28l one.

Great bag, looks great, comfortable to wear, durable, holds plenty of gear and is expandable. Never have to worry with the Thule quality and warranty - you get what you pay for. My only real complaint about the bag is I wish it had a slash pocket on the front to quickly stash small items.

First of all, use case is everything. On a long trip to Europe, we chose to take one carry-on and one personal bag apiece. This bag was my personal bag and was not meant to replace my carry-on. As such I wanted it to be as large and functional as possible, while still being able to fit under the seat. This it did magnificently. I was able to pack a a ton of clothes and other personal gear, electronics, etc. in his backpack. You can access the main compartment through the top or it opens clamshell style. It has a nice large sleeve for a laptop and a smaller one for an iPad. It has decent organization and an easy to reach outside pocket for things like chargers, keys, glasses, etc. You can also expand it significantly if necessary (this can also help compress the bag if needed). It is not too large to go as a day pack if necessary and it is quite comfortable. The zippers and pulls are all quality. I found the outer shell fabric to be very water resistant and durable. There is also a zipper pocket between the straps that easily and safely fits a passport or wallet. The water bottle pocket is quite large, but it was my one complaint. Because it is oriented straight up and down vs canted forward, it is quite hard to insert or withdraw your water bottle while wearing the pack. While this was a little irritating (and really should be addressed by Thule), it was certainly not a dealbreaker. I have to give the Thule Aion two big thumbs up! 👍👍

This is a well-designed, eco-conscious bag that's perfect for daily use or travel. I love the durable, water-resistant recycled polyester fabric. The standout feature is the removable internal rolltop bag, which is incredibly useful for separating items like shoes or wet gear. It offers great padded protection for both my laptop and tablet, and the top pocket is a handy spot for smaller items. It's comfortable to carry and highly functional – a solid all-around choice for anyone who values both utility and sustainability.

I really, really wanted to like this bag but overall the layout just doesn't work for my purposes. The positives are the storage space is great. I really liked the few small zipped compartments and even the divider with the wet pocket is nice. It's a sharp-looking, well-built bag - I really loved the zipper pulls.. Unfortunately the way the clamshell opens I'm not a fan of at all. To access the main compartment you lay the bag on its front, then zip open the back laptop open and have the bag completely laid open. There is no strap to hold the laptop in place, so you really need to have a large, flat area to lay the bag. If it was on a luggage rack for example the laptop would slide out. Additionally when open you won't be able to access the front pocket without closing it up and flipping it over. If you weren't planning on using the clamshell feature this would be an awesome bag.

Awesome backpack. Love it. It's great for travel. Lots of room for keeping different items separated. Clothes, shoes, toiletries and all sorts of room.
