I've used the Cabela's swede pants, with fleece underneath, for a while now. Does a good job but a little noisy for still hunting that do especially walking through briars.
Pluses- wind proof, water proof, light,durable.

Next year will try the Berber Fleece(very quite) with wind shear.
For still hunting wool is too heavy for me, itches and most aren't wind proof.
