I chose this brand because I want a school bag that is neither too heavy, tough enough, which provides good support to the back and beautiful countenance. I'm quite comforted. This portfolio corresponds to my expectations. The three compartments allow better organization of the affairs of my child. It is EC1. His first book bag purchased for CP was too worn! I had planned to take him to CE2. According to the brand that bag corresponds to CE2, CM1, CM2. So I preferred to take the bag format back because I find a bit wide formats satchels, and my son is fine, I find it better corresponds to its morphology. For robustness we will see in a few months ... I recommend!
