This is a Konny baby carrier. It's Air mesh, so it's breathable for the Summer. It can be used year-round because you sweat even in the Winter when carrying your baby. The size is L. The color is black. It does not have a head support. The support strap is unused. I'm selling it because my child has outgrown it, and I'd like to pass it on to someone who can use it. Please understand that this is a used item before purchasing.
