Hi! I am a very special backpack. I am equipped with a spectacular padded charm with carabiner and you can fill me with everything you need. What if you need more space? Simple, you can double it through the side zipper. This always having your well-being and your safety at heart! In fact, with the preformed Ergosystem backrest with integrated bottom and the padded and breathable shoulder straps I can protect your back! With the reflective inserts, I make you more visible when it is dark! Nevertheless, I'm also made to play! Have fun with friends to change the graphics with the FLIP SYSTEM, the system with magnetized flaps, and discover the spectacular SJ CARDS! With me, your day will be full of study, game, surprises and fun! Ready?
