Herlitz school bags are the only bags in Romania that are certified and recommended by the Romanian Pediatric Society. They feature a durable structure that is carefully padded to ensure ergonomics, equal distribution of pressure and weight on the spine, as well as ventilation for the back and shoulders. The position of the bag is fully adjustable according to the child's body shape, an extremely important feature. Proper fastening of the bag on the back, close to the shoulder blades and adjusted according to height, is the only way to prevent posture disorders, according to medical recommendations, and a requirement that Herlitz bags meet regardless of model or condition. Additionally, Herlitz bags have an ideal weight, under 1 kilogram, providing the foundation for healthy development.
