I'm pretty sure that by targeting recycled materials for many decades, Patagonia has been doing its best to separate itself from petrochemicals. I have a fleece that was given to me in the late 90s that was made from recycled plastic. Still works great.

It is a PR strategy from Patagonia, but not necessarily for sales. For as long as Chouinard is steering the ship, Patagonia's goals are much broader than financial success.
