Hi! I’m the amazing SJ Gang expandable backpack! I like to combine play and comfort to deal with school together with you in a playful way. I am equipped with detachable charm and FLIP SYSTEM: a system of flap flips with different graphics. Have fun discovering them all! It will feel like you have a different backpack every time! I have a large double compartment, which can be easily expanded, thanks to the side zippers for easy storage and organization, even with heavy loads. Thanks to the preformed Ergosystem backrest and the padded shoulder straps in breathable material, I am comfortable to carry on your shoulders, while the integrated bottom ensures that the shape of the backpack remains unchanged and stable, even with a full load.
