A backpack, satchel and briefcase are not synonyms, likemany think, but different kinds of bags. A briefcase is a stiff bag with one handle. It is not recommended to wear such a child: the child holds the briefcase with one hand, the load is distributed unevenly, which can lead to scoliosis. The backpack is not rigid and therefore not suitable for younger schoolchildren. But the knapsack with its hard frame and wide soft handles is ideal for first-timers. A rigid inner frame distributes the load, not allowing sharp corners of textbooks or pencils to crash into the back. The knapsack does not lose shape and does not crumple on the notebook. The orthopedic backrest consists of dense pads, covered with a breathable mesh cloth, which helps distribute the load along the entire back. This maintains the correct posture. The material of the knapsack is better to choose a dense, synthetic one. It is durable and easy to care for. The top edge of the knapsack should not rest on the head of the schoolboy, and the lower one should not press on the waist. This also helps to distribute the load evenly. Orthopedists say that a first-grader can not carry more than 10% of his own weight behind his back. Therefore, the weight of the empty portfolio should not exceed 1 kg. Be sure to evaluate the straps. Ideal - soft and fairly wide, adjustable in length. Light reflecting elements in the dark make your child noticeable on the road. This is a useful bonus. You can choose the perfect knapsack and backpack in stores.1 / 6Special for readers of the site wday.ru makes a 30% discount on all backpacks! Addresses of shops "Empire of bags".
