Plenty of space for clothes and my important items

Just purchased a Thule Aion and used it for my recent short trip. As I live in Hawai’i and enjoy traveling to the mainland and foreign countries such as Japan, Italy, etc. I wanted a big enough backpack that can accommodate jackets, etc. for colder weather so I can wear them as soon as I arrive at my destinations. This backpack has multiple slots and pockets for my iPad, iPhone, chargers, keys, passport, pen, etc. I can easily get them out. I have four other backpacks, but this one is so far the best one for my short and long trips. Would highly recommend it for avid travelers.

Love it!

I bought this backpack, the Thule’s Aion 40L a few weeks ago and test drove it. Here’s what I found. This backpack meets both the carry-on requirements of both domestic and international overhead bin measurements . It fits nicely on the overhead compartments of Aer Lingus and Delta Airlines on my recent trip to Scotland. It packs nicely with ample room for my clothes for 9 days. You can hold a lot of stuff in this backpack and it’s very comfortable to carry as a backpack. I got the Nutria color and love the waxy look!

Great Travel Pack!

I purchased the black/charcoal version. This is a great carry on pack that is versatile and not to much to manage once you reach your destination. The bag has room and depending on how bulky your items are can carry quite a bit but be cautious not to overpack as it will not fit without extreme force in smaller planes overhead. The ONLY thing I would cautious buyers is the look of the bag after use and when you receive it. The texture THULE mentions of having a weathered look if factual and when you use it will get more "weathered". The look is not bad just looks like you have used the bag for multiple trips after your first one. If you expect the bag to have a "fresh" look all the time this is not the bag for you. Durability is excellent, definitely recommend it.

Almost Perfect; Needs A Few Tweaks In Round 2

Some things I would like to see in the next update… 1. Load lifter straps above each shoulder strap to redistribute the weight closer to the body. 2. Side compression straps to compress the pack when not fully loaded, and to reduce the outer dimensions when you’re trying to fit the bag in an overhead compartment or other tight space. When this thing is fully loaded, it has a tendency to look like a turtle shell on your back; compression straps would help with this. 3. Slightly more interior volume. 42-45L would be perfect for one-bag travel 4. Include the hip belt pack instead of forcing people to purchase it separately. It’s an ingenious idea, but it should already be included. A travel pack this size NEEDS a hip belt in order to redistribute weight off the back and shoulders and on to the hips.

Amazing bag

I purchased this bag since I travel by plane once a month for a small amount of time and I wanted a nice carry on. This is such an amazing travel backpack. It has compartments for everything. I like how it’s versatile, I can wear it as a duffel bag, or backpack! It’s the perfect bag for a small weekend trip, or for a weekend plane trip! I love it.

perfect backpack

Hi!! Thule!! It's a perfect backpack. I use this backpack every day. Thank you so much for making a good bag! But when I travel for 2 nights and 3 days in winter, the capacity is not enough. I want to put on a small bag. Like a picture. please Make it. please feed back.

Great pack except for a couple of design issues…

This could be the perfect carry on back pack to fit all your electronics, medium trip clothing and accessories and then some. But I found at least two design issues that inhibits it’s full potential. I have used this as a carry on all g with a roll aboard carry on for a 8 day trip in the UK/Scotland. First, When the internal tie downs in the main compartment are cinched fully the zipper for the electronics compartment does not close smoothly. Second, when you stow the pack on your roll aboard handle you have to flip the pack on its side. Which means you can’t keep your water bottle in its pocket when carrying it this way as the bottle slot is on the side. Defeats the purpose!! Thule design team - maybe you will address in the next iteration. Happy to give additional feedback.
