The backpack for active days or weekends away

The bag's back panel fully unzips and opens like a suitcase for easier packing. Inside, a stowable divider with TPU lining helps to organize your gear while keeping moisture, odor, or dirt from spreading to contents in the rest of the bag. The travel backpack also has dedicated areas for electronics storage and a water bottle pocket. The Thule Aion Sling (sold separately) can be used with this backpack as a hip belt to bear extra weight and provide quick access to vital items.

Bluesign® certified and made from durable recycled materials

The shell fabric, lining, and mesh are made of 100% recycled materials. The bag’s rugged and durable waxed canvas fabric develops even more character as it ages and has a water-resistant finish that is free from toxic PFCs. All Thule Aion products are bluesign® certified, which ensures the protection of workers, consumers, and the environment.
