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". Its members, physiotherapists, physical education teachers and doctors, have contributed to the realization of this product. 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. Like trekking backpacks, they allow you to carry the weight for many hours, without tiring your little ones: they can walk, jump and play, even carrying a heavy load of books. 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. Furthermore, thanks to its fluorescent surfaces, it guarantees greater safety and visibility even in conditions of intense road traffic. The reflective material used is not only durable and of particularly high quality but also has a high luminosity coefficient, such that the Ergobag school backpacks reflect when exposed to a light beam of just 5 degrees. 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! Millions of PET bottles are produced every day all over the world to be emptied and disposed of. Countless bottles end up in waste in landfills or worse in nature. In countries where deposit systems are not yet present, PET bottles are collected, recycled and transformed by the Ergobag staff to produce backpack fabrics. So even waste acquires a value. Furthermore, all the fabrics and materials used are free of toxic plasticizers (phthalates) or PAHs (Polycyclic Aromatic Hydrocarbons). To further reduce its environmental impact 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.
