Synchilla
Chinchilla is 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.
