2025 Aion 40L Bigger than 2024 Aion
I bought my husband the 2025 Aion 40L backpack because I loved mine I bought in 2024. His backpack is definitely bigger than mine and I have to say I like my smaller 2024 Aion better. His backpack, with the size and various pockets, can be used for weekend trip luggage.

Almost perfect
Very well thought out bag that is much better than a traditional carry on. However three improvements would make it even better. 1) The water bottle pocket needs a way to secure the bottle. My bottle falls out regularly. 2) It needs a flap on the back to slip over the handle of your suitcase when you’re wheeling your luggage to the airport. 3) The clips on the straps inside are clumsy to use. A common buckle clip would be better

Thule great quality
I bought the Thule Aion 40L travel backpack and sling bag during the black Friday sale. The shipment was slow, but it was understandable because of the holiday's sales volume.
It's my first time owning a Thule bag and I am very happy with its style and quality. The travel backpack is very roomy and sturdy. I have not used the bag for travel yet as of this writing. It looks durable and like it can last for long time. I do agree with other comments that suggest the sling bag to be included altogether with the travel backpack. The bands of the sling bag (the bag itself is inserted into the bottom of the travel backpack and can be used as a hidden compartment) would help hold the weight of the backpack better. The Nutria (yellow) color option is more like light brown. I highly recommend these backpack and sling bag.

This backpack is the one to get.
I've used this for a couple of weeks now and I love everything about it. I'm 6 feet and 230 pounds and I found most backpacks to be uncomfortable for my size but not this one. It's well worth the cost. Quality and fit are top notch.
