^^^^ I’m a big believer in wool too, but usually just socks & sweaters. Both make a huge difference, especially in the mountains. 😉
One sweater is cashmere, which is great because it’s thin enough to breathe well, even when it’s warm out.
We seem to be going through a wool socks shortage, here in the U.S., it’s getting hard to find them in stores. 🤔😉
