Woolrich has carried the name of America’s oldest continuously operating woolen mill since 1830, and the Green Label Collection is their marker for classic American casualwear. This long sleeve pocket tee is built from a heavyweight 60/40 cotton-polyester blend — substantial enough to work as a standalone layer in cool weather or under a flannel when temperatures drop further. The chest pocket and relaxed cut keep it firmly in everyday territory. In a heathered charcoal gray that goes with just about everything, it’s the kind of shirt that earns its place by being exactly what it needs to be.
