Thule Aion Travel Backpack 28L | Expands to 32L, Dark Slate

Meet the Thule Aion 28L Travel Backpack — a bag that grows with your day and your plans

The Thule Aion Travel Backpack 28L is designed to flex with your routine. It easily expands from a compact 28L daypack to a 32L travel backpack, adding 15% more packable space for when you need to carry a few extra items. Whether you’re commuting, gym-going, or planning a weekend away, the Aion helps you stay organized so your essentials stay within reach.

Smart, adaptable capacity

Expanded capacity is more than just volume: it’s flexibility. With the click of a zipper, this backpack accommodates a change of clothes, a compact travel kit, or on-the-go gear, while the core 28L silhouette keeps everyday items comfortable to carry. The finish remains durable and easy to clean across daily use and travel.

Smart organization that travels with you

The standout TPU divider keeps items separated and reduces the transfer of moisture, dirt, and odors between zones. It tucks away when not in use, helping maintain a neat interior. A zip-top pocket secures small items, and an external stash pocket offers quick access when you’re on the move.

Compatibility and versatile carry

When you want extra support, pair the Aion with the Thule Aion Sling Bag — sold separately — which doubles as a hip belt. This option can enhance stability without adding bulk, making it easier to move through airports or crowded streets.

Real-world scenarios and benefits

From daily urban commutes to weekend escapes, the Aion adapts to your rhythm. You could tuck a lightweight jacket and chargers into the expanded space for longer days, while keeping your laptop and everyday essentials organized in the divider system. The bag’s external pocket invites quick grabs, and its dark slate finish fits both city and outdoor environments.
