Your Go-To Backpack for Adventures

Meet the versatile Thule Aion 28L backpack, which easily converts from a compact daypack to a spacious 32L travel backpack, giving you 15% more room for all your essentials. It's got a handy divider to keep your daily items separated from your outdoor gear.

The back panel zips open completely, transforming the backpack into a suitcase style for hassle-free packing. Inside, there’s a removable divider equipped with TPU lining, designed to keep your gear organized while preventing moisture, dirt, or odors from spreading to your other belongings. It also features special compartments for your electronic devices and a spot for your water bottle. Plus, don't forget about the Thule Aion Sling (sold separately) that can attach to the backpack as a hip belt for added comfort and easy access to your must-haves.

Eco-Friendly and Built to Last

Crafted from 100% recycled materials, the exterior fabric, lining, and mesh of the bag are durable and sustainable. The waxed canvas outer layer not only ages beautifully but also boasts a water-resistant finish, free of harmful PFCs. All Thule Aion products carry the bluesign® certification, ensuring safety for both workers and the planet.
