Thanks for the welcome!
For some reason everybody I've heard talk about Sportsmans Guide fall on two extremes: Love them for the price, hate them for the service. I was leery ordering from them until I saw a few people mention that they actually got their wool pants as advertised.
My first foray into wool was ordering a Swedish wool great coat off US Cav. Sucker weighed a ton, and was unfashionable as heck back in college, but kept me warm. So much so I then ordered a pair of Swiss wool combat pants, which was even more unfashionable (leather ankle garters?!). They were cheap back then too, I think US Cav was clearing them out, $50 for the coat, $20 for the pants. The same coat and pants are going for more these days.
I think my next wool purchase will be a Schott pea coat. Not cheap though...
