This backpack has so much to it it’s hard to know where to start! Firstly, it has 2 good size outside zipped pockets. The first zipped compartment has a mesh pocket, a charging port, 2 slip pockets and 2 pen pockets. The middle compartment zips round so it opens up like a case. There is a waterproof pocket for any wet items, a zipped mesh pocket on one side and the other side has elastic bungees to hold your clothes in place. The third zipped compartment has a laptop compartment, a place for a tablet and another slip pocket. The back of this backpack is padded and there is a hidden zip pocket ideal for keeping travel documents. The size is compatible with EasyJet underseat cabin size.
