The alpaca breed known for its long, hanging fleece is the Suri.
Suri alpacas grow fine, lustrous fibers in long, separate locks that hang close to the body. The locks may look like silky cords or dreadlocks, giving the animal a sleek, draped outline rather than a rounded, fluffy appearance.
The main comparison is Huacaya, the more common alpaca type. Huacaya fleece grows outward and has a crimpy, woolly texture, while Suri fleece is straighter, more lustrous and generally better suited to woven textiles. Suri and Huacaya are the two recognized alpaca fleece types, not separate species.
Alpacas originated in the Andes and were domesticated from vicuña-like camelids. The Suri is much less common than the Huacaya, so its distinctive coat is especially valuable to breeders and fiber producers. “Llama” and “vicuña” are related South American camelids, but neither is an alpaca breed.
