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.

This is a really nice looking backpack with some useful features and pretty comfortable to carry too. Really solid construction with awesome zippers and nice water resistant material. Things I like... - Really nice zippers - looks nice - expandable from 28L to 32L - few good little organization pockets in front - stash pocket in top back - nice interior setup that can be split or used as one large compartment - interior thin waterproof section to keep papers dry OR separate something wet or a few dirty clothes - comfortable side carry handle - fits 32oz Nalgene bottle - luggage pass through Changes I wish it had... - remove that front little handle, looks weird sticking out. Just make it a little incognito strap if you gotta put something there. And back top handle not comfortable to grab, make it a little more comfortable - wish front had a quick access zip pocket for little stuff - wish there was a better dedicated pocket on top to stash and protect sunglasses - the little zipper pulls on a couple zippers sort of stick out and wish they just laid against bag - maybe a couple more little zipper stash pockets inside would be good - wish bag was like 1-2" longer top to bottom (I'm 6' tall) so it would just fit more long ways vertical on back as opposed to sticking further out. Overall a really solid, nice looking, functional bag w some great features and better than 95%+ of what you'll find in this size and price range.

This backpack has been excellent. The construction feels high quality and very durable, and it has held up extremely well as my everyday work and computer bag. One of the best things about it is how versatile it is. When it is not packed out, it keeps a relatively compact footprint, but it can expand enough to handle several days of clothes for a quick business trip. That makes it a great option for someone who wants one bag that can pull double duty for daily use and travel. Overall, this is a well thought out, premium-feeling backpack that I would absolutely recommend, buy again, and give as a gift.

There is much to like about the bag. The layout makes sense, sippers good quality. I have had it for over 18 months and no REAL complaints. I will say that I purchased a number of Thule packing cubes around the same time I got this and those have been really handy. You could do a lot with this bag plus a few cubes if you wanted to freeze up space in your checked bag or carry-on luggage. Only minor nits are: 1. It does not want to stand up. Worse, instead of wanting to fall back it wants to fall forward. That seems to be true no matter how I load it. That's not catastrophic but it is a hassle. 2. The exteriors materials (a sharp looking black color to start with) fade to a black/grey of time. It's possible it could be rehabilitated with some sort of cleaner/protector and I have not tried that (it doesn't look outright bad as it is, just less sharp than it once did). You would think, well... OK some wear that makes sense it'd fade. But the material itself is truly robust. It is NOT worn and show no signs of tattering or abrasion, just a bit of a fadd look now. I do like the brand, and I'll keep using this for some time I'm sure. When I do finally move on to another I will not miss one bit the weird tendency of the thing to fall forward when it's set on the floor. I still haven't gotten used to that.

I highly recommend this expandable (28-32L) TRAVEL backpack. Many companies make mediocre products to complement their better known merchandise. This is not one of them. The backpack is made of partially recycled material and has a canvas like water resistant exterior. The handles are well thought out and there is an elastic side bottle holder. The pack opens separately from a top zip or full clam-shell style and is lockable. It also has a handy waterproof compartment to hold a wet swimsuit, etc. The Aion contains two padded compartments to hold your tablet and a large laptop. There is a top zippered pocket that holds your small items like earbuds, cables, etc. The shoulder straps are comfortable and have an adjustable cross strap. The above pics show these features. After using it on a four day trip I think it's a well thought out and high quality product. It also fits under an airplane seat. Thule has made a great backpack. Who knew?

The most versatile backpack I've ever had. Quality - A+. I own several Thule products, and this is my go to for light to medium travel. Fits all clothing, paperwork, toiletries, accessories etc. Excellent laptop protection and easy access compartment for carry-on. If you spend the night anywhere but home, this backpack is a necessity. Stow the straps and carry with the side handle if you'd like. Also fits perfectly and tightly on a roller. Excellent value for the money.

As a travel bag, this is the perfect size with lots of room to pack stuff for traveling. Padding around and inside is really good and the shoulder straps feel good too. The main issue I have with the bag is that it carry crooked when the shoulder straps are the same length. Not sure if this is a design flaw or how the bag is made, but there's no way to shift the bag main compartment centered since the stitching and material won't allow it. Therefore, when wearing the backpack it sits at an angle and looks very weird. It sits on the shoulders just fine with the same amount of distance from your back, but if you loosen the right strap to drop the bag down then it moves away from your back and creates a lot of space and feels off balance. I have other Thule bags and really like the quality of their products, but this one is just built weird and isn't symmetrical looking, even when it's sitting on the ground.

My life's goal has been finding the best bag for a specific purpose and I have achieved my goal, in the area of daily driver backpack /short weekend trip backpack --- this bag is great, it's big enough for my lunch, headphones, laptop, another layer, etc for my day out , and it expands for a weekend away. 2-3 days max tho. The "luggage" type thing is really useful for the weekend, and u don't even notice it if u use it for just the day. It has a tiny easy access pocket for like, charger, Advil, etc. Honestly it's just good. It works great, is comfortable, very padded , AND LIGHTWEIGHT !!! I've tried other bags (looking at you, Aer from SF) and their padding is so friggin heavy, and the bag is so overpadded you can't fit your lunch in there. Anyway I love this damn bag, I think it's water resistant too. I should have known Thule would make a banging bag!! Much respect to this bag and whoever designed it. Bang up job
