Vanquest PILUM VSlinger
Sling bags offer a backpack's storage space with a messenger bag's ease of access, in theory at least. In practice, they can be hard to balance on your back and shoulder, sometimes making them awkward to carry. Unlike other sling bags, the Vanquest PILUM VSlinger accounts for asymmetry in its design. In fact, there are two versions of this bag for both left-handers and right-handers. Each version swings to either the left or right, and both offer easy-access to your gear.
The VSlinger can accommodate a 15" laptop and a bunch of camera gear if you need it. It has 19 total pockets for you to use to both carry and organize your essentials. Internal dividers in the main compartment allow for further organization options. Thanks to its strong padding and water-resistant 1000D Cordura nylon with Teflon, you can take it anywhere. Its minimal amount of MOLLE webbing also make it better suited for urban carry while still offering modularity when you need to carry more.
Whichever version you choose, you'll find the VSlinger is easy to use with the hand you find most comfortable. You only have to pick the one that corresponds to your handedness and your needs. Pick one up for yourself at the Amazon link below.
