We love our Thule luggage and back packs! Wouldn’t use anything else.

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.

Perfect Travel Backpack

I bought the Aion 40L backpack to use as my carryon while traveling internationally. It’s a great size… not too heavy when fully packed. I put all my “can’t be without/lose” things like meds, chargers, wallet, passport, phone/tablet, etc in it. It easily fits in the overhead and sometimes under the seat depending on the airline. It has a pocket or space fit everything. It’s well made and very durable. It fits comfortably on my back except I don’t like, need or use the chest strap.
