This hip seat carrier is made of breathable mesh material for comfortable babywearing. It can be used as a hip seat alone, or as a baby carrier or back carrier by connecting the included parts. It can be used for a long time, from infancy to when the child starts walking. As it is a hip seat type, it reduces the burden on the lower back and shoulders. It also has pockets, making it convenient for carrying money and a smartphone when going out for a short time. I purchased it in 2022 and used it for about a year and a half. Thank you for looking.
