Wait, the "fleece" jackets are made of plastic??
You're not talking about the outer layer of the down jackets?

I do make a lot of winter trips like the one in the photograph (long winter backpacking trips) and am an instructor and I only use wool for my socks and other undergarments, and jackets. Down for sleeping in. Synthetic underpants though!
Other than that, a wool felt is quite nice.
But at least wool can be repaired.
Yeah and people who buy Patagonia fleece expect it to be made from recycled water bottles
