The best
Bought this for travel and work, and it's the best designed backpack I've ever used. Every pocket has a purpose and makes sense, the zippers are sturdy but smooth, it's user friendly in every aspect, and you can fit a ton of stuff in here. I'll use this backpack until it falls apart. Highly recommend.

Love Aion
Debating between Aion and the Subterra. So glad I chose Aion. Easy to carry due to the shoulder straps, fits a ton of stuff and light.

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
