The title is little confusing but it simply means that this bag can be used as all in one bag. It has been designed to let the traveller have a comfortable trip. The bag is attached with handles on sides as well as on the top. There are two durable straps to make it a backpack/rucksack. A shoulder strap can also be attached for using it as a shoulder/crossbody bag.
The bag is made from 16oz Canvas material with 100% cotton material inside. It gives the traveller a unique vintage look. Being made of Canvas and cotton, the bag is not waterproof, so for summer or winter purposes only. The bag is designed with many utility pockets including secret protective compartment. A great deal at $46.
