The Thule Aion Travel Backpack is a bluesign-certified bag made from durable, recycled materials. The robust and long-lasting waxed canvas exterior develops even more character with age and is treated with a PFC-free water-repellent finish. The back of the bag opens like a suitcase, making packing easier. Inside, a stowable divider with TPU lining helps organize your gear and prevents moisture, odors, and dirt from transferring to the rest of the bag's contents. Special compartments provide space for electronic devices and a water bottle. The separately available Thule Aion Sling can be used with this backpack as a hip belt to distribute extra weight and allow quick access to essential items.
