Is it a backpack or a pannier? Yes.
If you are looking for a commuter pannier that you can also throw over their back, this is it. Holds 28 liters of cargo, including your your 15.6-inch (or smaller) laptop, keeping it safe and dry. Mounts to your rear rack with one easy click.
When you carry this into your destination, it doesn’t advertise that you arrived by bike — you get to decide whether or not to boast about that. The stowable attachment system gives you the best of both worlds, making it easy to switch between backpack and pannier modes. The side compression straps cut down on extra bulk while walking or riding.
Weeks after using the bag, you’ll still be discovering features.
