The Carhartt Men’s Washed Duck Sherpa-Lined Mockneck Vest is a cozy vest for the changing of the seasons. Think summer into fall, all winter long, and straight into spring. The cotton washed duck exterior is hard-wearing against the trails and work day, while the Sherpa lining is super soft and warm. Wear it over your favorite button up plaid shirt, heat your center, and take on the day. Colder outside? It’ll act as a warm midlayer underneath a shell jacket.
