The versatile sling bag. The Thule Aion sling bag is a modern hip pack or crossbody bag that gives you quick access to all your most valuable items. The internal divider and zippered pocket keep everything organized, and the key fob lash point secures your keys. When you're traveling, the hidden exterior security pocket is the perfect place to safeguard your passport, ID, or cash. The Thule Aion sling bag doubles as a hip belt when used together with Thule Aion backpacks. 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. Tested to the limit. At the Thule Test Center in Hillerstorp, Sweden, products go through extreme testing.
