The Wool Atelier Overshirt is crafted from a midweight (340gsm), 100% Merino wool in a twill construction which gives the feel of a jacket rather than a typical overshirt. We've updated the styling slightly with a 4 larger button fastening on the placket. Cut a touch longer through the body than our original Atelier Overshirt. Regular fitting. If you're normally between sizes we recommend taking the smaller size in this style. Dry clean only.
