I am selling this item because my child outgrew it without using it. Please refrain from purchasing if you are sensitive to items stored by a non-professional. This vest is convenient for regulating body temperature for newborns to around six months old. The outside has easy-to-use hook closures, and the inside has string ties that can be adjusted as your child grows.
