This is a Konny baby carrier. The size is XS. It's a full mesh type, so it's extremely breathable! It's made to be durable even when put in the dryer, and I washed it every time. The mesh type is light and highly elastic, which is a key feature! You can use it from newborns, so you can use it for a long time. I used it until about 4 months old. Includes outer strap and storage bag.
