The Kid's Popoyo Bag children's backpack from MeroMero is perfect for school and exciting outdoor adventures! It is super lightweight and particularly comfortable with its padded back, 3D mesh shoulder straps, and adjustable chest strap. The double roll-top closure system features a magnetic closure and a regular clip closure, allowing the backpack's volume to expand from 7 to 10 liters. A padded inner sleeve protects the contents of the backpack from impacts. The ventilated mesh back inserts ensure good ventilation during physical activities. The waterproof and durable fabric is PFC-free and made from recycled materials. Reflective straps ensure that little ones are more visible at dusk.
