I just checked my Patagonia 1/4 zip top and it's "100% wool, exclusive of trim." It feels like it too. Great top for the money IMO.
Interesting. The Patagonia website says the same thing. Next time I see the Patagonia rep I'll ask him how this meshes with what he told me (see previous post), as he stressed how they used synthetic fibers to create a thread that would hold together without chemical treatments.
BTW, I wore that Mammut base for the last three days, and while it wasn't the most intensive test, I remain optimistic. Comfy, dry, and odor free.
