1. COMFORT AND SAFETY: You can hold the leash in your hand to control the activity area for children in the mall, supermarket, park, zoo and other places where many people are and prevent them from getting to dangerous places such as roads and rivers, keeping the child close and safe. 2. Relieve your shoulder fatigue: the baby is much smaller than adults, you can have back pain because you bend over to pull the baby. It is also easy to strain your child's arm. With our anti-lost backpack, you no longer have to hold the child, just pull the leash and it will be much easier. 3. Healthy and stable materials: made of high-quality environmentally friendly Oxford cloth, metal hook, adjustable shoulder strap. The backpack made of environmentally friendly Oxford fabric material passed CPC certification. Removable metal hook for durability. The shoulder straps are freely adjustable for all ages, whether you wear thin summer clothes or thick winter clothes. 4. Give your baby free space: the baby's favourite theme is not to be pulled by the mother, but to run happily. You can put the children's lead in a safe place. At this time, the anti-lost backpack becomes a favourite toy for children and gives your little one the freedom and confidence to walk alone. 5. Nice, comfortable and practical: our anti-lost backpack not only has the cute shape that children love, but also very practical. In the main compartment with zip, you can put nappies, play towels and a small snack that your baby likes, so that you can use it at any time and improve your children's self-care ability.
