The brand "Big Bill" (Codet) is commonly found in Canada. I've seen pants in 2-3 different models and 2-3 colors varying from 75% recycled wool to 100% virgin wool. They are made in Canada, therefore less expensive to buy here and you save shipping, duty, etc. Look for them in places where they sell work clothes.
In November I bought a dark green pair with cargo pockets for myself that were 75% and a pair of grey with pin stripe without cargo pockets for my wife that were 100% new wool. I have four pair of wool pants of different thickness, color, and quality (one King of the Mountain) but the prices were good and I couldn't resist.
Sorry, I had confused Codet with Cadorette.
