Unlike the Deuter carriers, the backrest on this carrier only goes up to the neck of most children 2 years old and above. There's no place to rest their head on or a cushion to protect their heads from falls.
This carrier comes with a load stabilizer, allowing you to adjust the backpack's center of gravity. You can do this by pulling the webbings near the shoulder straps, which also pulls your child closer. As a result, your child feels lighter and it's more comfortable to carry him.
The child shoulder straps are a bit flimsy and do not have sufficient padding for a comfortable ride. If your child is only wearing light, loose-fitting clothes, these straps will definitely dig into your child's skin.
