A bunch of the wool stuff that's so trendy among HN-reader sorts the last few years is supposed to be dry-clean only. Though I think some folks just rarely wash it, and hand-wash in a sink or something on the rare occasions that they do.
Yeah, I think a lot of the merino wool stuff--which I use as well--is to basically not wash it a lot and maybe do it on gentle or in a sink when traveling when you do.
Fair enough. I've found wool to do pretty well in the wash but of course no dry cycle. Merino can hold up surprisingly well and not shrink much if any, in a dryer
