I'm more concerned with fabric performance than it being dead quiet. Quick drying, a little stretch, breathable and easy maintenance...just throw in the washer.
Wool is a great fabric...but not easy care.

I treat my first lite wool like any other clothes I have... they have been washed and dried lots of times and are still kickin'
the only high maintenance clothes I have is my rain gear, I still wash and dry it, but pull it from the dryer before it's completely dry and hang dry the rest of the way. a hot dryer will kill any high end rain gear, and that's an expensive mistake I have made the hard way.
i'm with ya though, besides rain gear, if it needs special care, I don't want it. I do value quiet material, my pant legs will be brushing against stuff on a stalk, there aren't many square feet of habitat around here that are clear of some type of brush.
that being said, I have snuck up and shot sub 20yds on a lot of critters in all types of pants. my corrugate guide pants are probably my loudest, but they have DNA of several animals on them.... it's usually not a deal breaker..... don't know my pants have ever blown a stalk.
I do remember one stalk last year on some elk, it had poured all morning and I had a full set of chugach on, and I found some elk feeding in a cut.... it was open but I had the wind and decided to try.
once I got to about 60yds those pants were irritating me, so damn loud now that it was nice calm weather.... I was laying on my back in the open slowly wiggling out of all of my rain gear, and just left it there on the hill side...… in the end, I got a shot at 14yds, but that day the trad life was the sad life.... he trotted a few steps, stopped about 20yds, and the thought of reloading another arrow didn't cross my mind, but throwing my bow at him did, haha.
rain gear in the rain isn't bad, but when it's still and silent it's really bad
