Columbia has two kinds of wool clothing, so you might be careful which you buy. The Columbia Gallatin wool is only 65% wool (recycled wool) and the rest is man-made materials. I have it and it is very warm, but it is not as warm as real wool when it gets wet. It is also considerably bulkier. Their Horn Mesa line of wool is 90% wool and is much better overall, but it can be tricky to find. You can find it on sale, but usually in odd sizes, plus the camo pattern is not as good as the Gallatin.
I like the looks of that Browning line!
