Thank you for viewing. This is a babybjorn mesh baby carrier, the One Kai Air model, in an anthracite color that is easy to use for both boys and girls. My husband, who doesn't like the back buckle type like the Ergobaby, purchased this new 4 years ago and used it for two children during the period from before their necks were stable to before they could sit up on their own (around 0 years old). I think the total usage period was about a year. The condition of the item is as shown in the photos. He also attached a cover from LucaCo because he didn't like the baby carrier to sag. Since our youngest child is now one year old and we use a hip seat, he said he doesn't need this anymore, so I'm selling it. It was used when going out, so there is some wear and tear, but since it had a cover, there are no major scratches or damage, and I think it can still be used. *If you have any concerns, please feel free to comment and I can add more photos. Thank you.
