Just a note, they are fleece and not wool.

In addition to B Corp, other third party certifications like Fair Trade and Blue Sign are a little more specialized but are generally good indicators of labor conditions.

In my opinion, the Jackson Glacier Parka is the best for the money and covers a wide variety of winter conditions. The Down Drift Parka or Jacket are excellent too.

Edit: meant to comment this further down in relation to the Patagonia recommendation. These are all Patagonia products.
