Is that a shirt, a jacket, or a great excuse to go outside? On those days when a walk to the woodshed doesn't require an overcoat, yet calls for more than an undershirt, this heavy-duty-lightweight-wool offers a generous cut and casual comfort. Plus the peace of mind that comes with never having to figure out what to wear. Generous cut, unlined. 17-19 oz. Dry clean only. 80% Wool, 20% nylon.
