Seamlessly transition from an active day to a weekend away

The Thule Aion 28L backpack, 40L backpack, duffel and carry-on luggage all have specialized packing areas that separate wet and dirty active gear from other items. You can also combine the bags to utilize new functions. The Thule Aion sling, for example, doubles up as a hip belt when used with the Thule Aion backpacks.
