The Ergobag company has combined the fundamental characteristics of trekking backpacks with those of school satchels, thus creating truly unique products. In particular, the Ergobag Prime backpack model is an ergonomic backpack that has a capacity of 20 liters and, thanks to the adjustable backrest, will grow with your child. For this company, your children's health is essential: their satchels have been tested by industry experts, such as the national IGR association, which operates under the slogan "We strengthen your back". The adjustable shoulder straps and the lumbar belt ensure the distribution of the weight on the stable pelvis of the child, lightening the work of his back. The shoulder straps have an adjustable front lacing, which additionally stabilizes the load. They are easily adjustable, and will accompany your children for many years of their school career. In fact, the backrest is equipped with a dimensional scale for adjustment, as well as being breathable and padded, to ensure maximum comfort. For the Ergobag company, safety comes first: for this reason they have equipped their school backpacks with large surfaces in reflective material, thus ensuring good visibility of the shoulder straps even in the dark. These backpacks are not only the best choice for the safety and comfort of your children, but they are also an environmentally friendly and ethical choice. They are in fact entirely made of PET, that is, they are created from recycled bottles! Furthermore, all the fabrics and materials used are free of toxic plasticizers (phthalates) or PAHs (Polycyclic Aromatic Hydrocarbons). To reduce its environmental impact even further and to amortize its cost, this backpack is designed to last for many years. For this reason, Ergobag has decided to make them customizable with motifs attached with Velcro, so that your children can always make them new, changing their look. There are several adhesive disks (kletties) decorated with fire trucks, princesses, dinosaurs and many others… your children will be able to indulge their imagination according to their tastes. In the backpack of the set you will find a practical, very roomy case, equipped with a divider and accessory holder that divides it into two floors. The set also includes a transparent notebook holder: keeping order in school backpacks has become easy thanks! Lightweight and very comfortable to always keep books and notebooks close at hand (protecting the corners from ears and bending).
