The XXL Backpack comes with three different size compartments. The biggest one has an extra pocket for your laptop. The middle one comes with handy pockets for e.g. pens.
Since the backpack has a USB-charger, you can simply charge your phone with the help of a power bank* or your laptop at all times.
The backpack is made out of waterproof material and keeps your stuff safe, even during bad weather. It has a clip on the front, so you can fasten it in front of your chest guaranteeing an even safer fit.
On the sides you can find some additional pockets for a shaker, a bottle of water, fruit, or something else.
