A perfect outer layer for the colder side of the fall and the beginning of winter, this field parka from Brooks Brothers is a water-resistant shell with a classic patch pocket design. The waterproof twill gives you protection from the elements and resists wrinkling, meaning you can roll it up when you pack without worrying about it creasing. The parka also comes with a hideaway hood for the rainy days and is half-lined putting it in the sweet spot between warm and lightweight.
