The Pugo 3.0 Plus Smart Backpack signifies smart organization and smart learning for children. It features a multi-functional storage space that allows for adjustable partitions using hook and loop fasteners, accommodating textbooks, flutes, abacuses, and other elongated items required for their courses. The interior of the top flap includes a large mesh pocket for storing pencil cases and jackets, effectively utilizing the internal space of the backpack.

Inside the front flap, there is a transparent mesh pocket that allows children to easily locate items and learn effective categorization. The outer side of the front flap is designed with a modular six-point snap button system, allowing for the interchangeability of handles and patterned front flaps. This enables the backpack to have versatile styles and the ability to replace accessories with different functions, fostering creativity and daily coordination.

After two generations of backpack designs, the smart backpack introduces the world's first detachable butterfly-shaped shoulder straps with three-stage adjustments. Inspired by the concept of a pendulum-style load-bearing system, the load-bearing core is positioned at the center of the spine, reducing the uneven distribution of weight even when the internal weight of the backpack is imbalanced. By utilizing hook and loop fasteners and five woven straps, the appropriate position of the load-bearing core can be adjusted according to the child's height. Combined with the curved design of the back, the backpack fits snugly against the child's body curves in all areas, achieving shock absorption and pressure reduction effects. This ensures balanced development of muscles and bones during the child's crucial growth phase.
