Chinchilla is a napped material made from fine wool. The surface has tufts very close together.[1][2][3][4]
The development of chinchilla was a milestone fabric in the evolution of fleece. "Synchilla" (Synthetic Chinchilla) was the first generation fleece. In 1985, Synchilla was used in product "seminal Snap-T pullover" from Patagonia, Inc., which was popular in ski trips across the Northeast.[5]
For many, many years, Synchilla was the Kleenex of fleece, if you will.

Chinchilla is an imitation of a textile made from the fur of the chinchillas, the South Americanrodents; the fabric pile is curled up in tufts.[1]
