This is some real grownup jazz. The classic mac overcoat with a bossy silhouette. Wear it rain or shine, but especially when it's pouring outside: Fully seam-sealed. Bonded cotton cloth from British Millerain, a 6-generation textile manufacturer and Lancashire, England-based world leader in specialist textiles for outerwear. Go ahead. Forget your umbrella even though the forecast said rainstorm city. The Big Win will be in its absolute element.
