Basic black stretch Kangaroo Korner All-Season Ajdustable Pouch sling.  This is not a cotton blend fabric - rather, its content is 58% polyester, 36% rayon and 6% spandex which makes this very stretchy, but still supportive.  Black binding.

The KKAAP makes a great baby carrier for children from newborn to toddler.  This baby sling is also a good choice for preemies.

Made in the USA.
