My brother has a heavy KOTM shirt-jacket that he purchased about 25 years ago. It is still going strong, and he uses the crap out of it. It's not warm enough for cold wx stand hunting around here (which is often in the low teens or single digits) and it's too warm for tracking in most weather, but good for sitting between about 15F-32F. I think the company may have gone out of business a few years ago, and is now back--I'm not certain of that but I looked at one point a few years ago and could not find anything--but that's my impression, so it's possible it is different than in the past. But if it's the same stuff, it's the best wool camo I've ever seen (compared to silent predator, sleeping indian, llbean). I have some lighter wool I prefer over bro's jacket for tracking, but if you can get the weight right for your use it's fantastic stuff.
