Jannik Medium Backpack


The ultimate backpack for all your city trips. Jannik Medium Backpack closes its main opening with a high-quality metal/plastic buckle. An additional zipper closure on top even allows you to load the backpack to the maximum and securely locks the flap top. The backpack comes with a large front pocket with a flap. A quick access on the rear allows you to enter the main compartment through a vertical zipper.

This backpack retains its matte-decent finish in daylight but at night, it will become highly reflective. Thanks to our custom material, microscopic glass beads will send back light to its source providing an extra safety feature while biking or walking. Each backpack of the Phantom Series is created using around 20 plastic bottles advancing the sustainable attitude of our products.
