The NanoTough fabric is highly water-resistant and designed to handle light rain and splashes, keeping your gear dry during transit. However, it is not fully waterproof, so it should not be submerged in water.

It includes an inner mesh pocket and a zip end pocket, which are useful for separating smaller essentials like chargers, toiletries, or travel documents from your main gear.

The harness system is designed to be stowed away when you want to use it as a traditional duffel. It also includes an adjustable sternum strap to help distribute weight comfortably when you are wearing it as a backpack.

The webbing loops and lash points allow you to attach extra gear to the outside of the bag, such as a sleeping pad, a jacket, or other accessories that don't fit inside the main compartment.
