I was thinking of buying some wool blankets for backup emergency use. Lighter, higher-tech stuff is probably better for backpacking and planned excursions. When I was younger I was more into high-tech outdoor gear. Now my adventures are more modest.

And for the more mundane (but more common) around the town things, I prefer the lower-tech. Around town I don't wear expensive down jackets and the latest in breathable raingear. I wear good 'ol Carhartt coats. Tough as nails, very warm, highly water resistant, easily washable, horse hair doesn't get all embedded in them, ... just all around rock solid. But Carhartt stuff is not lightweight (which doesn't matter around town). I think of wool blankets like Carhartt coats. Low tech, heavy, but for common needs, hard to beat.
