he fact that there are multiple designs to choose from is great! I chose the turtle because I thought it was very cute. It’s very lightweight , & does its job. It doesn’t bother my baby at all. It’s like a mini backpack for him to wear. He freaked out falling on the back of his head expecting to actually hit his head, his eyes got so big because I know he was expecting to hit his head. The strap across the chest is adjustable which is very good!
