This is a set of two Konny baby carriers, size S. The brown one is made of cut-and-sew fabric, and the navy one is mesh fabric. Only the brown one has a waist strap. There is also one set of instructions and a drawstring bag. Personally, I found them very easy to use, and I used them almost every day from about 3 to 6 months old. I originally received both of these from someone else, but they are in good condition except for some overall minor wear on the brown fabric. I think they would be a good size for someone who usually wears a size M clothing or a slim man.
