Versatility is what this bag possesses. It can function as a sling bag or as a bag pack. Due to changing the position of the bag, it can be adjusted to be slung with the same straps of the bag pack version. It is rather thin but durable, enabling it to be folded up & kept at a later stage should such a need arise. Since it is portable, it can be used for long distance travels as it provides more space after unfolding. The colors are also quite distinct & provide as way to immediately locate it & either fold it or lug it.
