The Ergobag WonBearland Prime Rucksack Backpack is an awesome ergonomic option for your kids. The WonBearland backpack features a hip belt and chest belt to help distribute the weight and support good posture. The padded hip belt will take weight away from the shoulders and distribute it to the stronger pelvic area. Featuring a stabilizing aluminum frame that can be adjusted for different heights so this bag can grow just as quickly as your child. There is an interior pocket to hold their books close to their backs to decrease the leverage effect. The front pocket has a magnetic buckle for easy access and is big enough to hold a water bottle and a lunch box. There is reflective fabric on the bag to ensure your child is always visible. The backpack has four feet on the bottom of the bag to protect the contents. Finally, the fabric is made of 100% recycled PET bottles to get your kids started on saving the planet.
