My 'go to' winter work wear is Carhart ( black lined) bibs and hooded jacket which by the end of the season, have usually taken on a petina similar to fine antiques and an essence of diesel fuel, chain saw oil, wood smoke, and horse poop.

For more social engagements, an assortment of Eddie Bauer parkas and jackets fill the bill depending on the activity and dresseyness of the occasion.
