This shirt jacket from Brooks Brothers is the perfect outer layer for lower temperatures and extra chilly days, making it an ideal three-season piece. Bonus: Its rugged medium-wale texture gives it a classic workwear appeal. Designed with plaid flannel inside the yoke and collar band, it's the perfect choice for guys who don't like coats. It's crafted in soft cotton with a touch of stretch for ease and the freedom to move without restriction and is versatile enough to pair with jeans for the weekends or dress pants for the work week.
