This is the official Slingling made in Seattle Washington. These slings make it sooooo easy to wear your baby. The babies love it and Mom will too! The slings are beautifully made and very sturdy. I looked over one myself and having a degree in Fashion Design, I am able to tell you that I was very impressed with these Slinglings! The materials are great (and there are many to choose from), the slings are padded and double layered. There are no seams to see anywhere. This is a great quality sling and worth every penny!
