I know that this isn't a popular viewpoint with many, but I have found modern technology with fleece to trump wool in almost every regard.
Wool is nice, but I almost bought wool and instead opted for a pair of fleece bibs, a fleece vest, and a fleece pullover. Got them all on 70% off blowout sale at Cabelas. Normally would have been almost $600. Got for $130.
The bibs are Fleece, waterproof, breathable dry-plus, Thinsulate, Gore-tex, Scent-Lok, wind-shear, and have padding in the knees/elbows, and even a really thick butt pad for sitting on the ground.
Also, you can machine wash them and dry them in the dryer unlike wool.
