The CPO Overshirt | Indigo Ash Wool Herringbone

A cold-weather staple that balances utility with understated refinement, The CPO Overshirt in Indigo Ash Wool Herringbone features a beautifully heathered, dual-tone weave that nods to vintage naval overshirts while landing squarely in the modern wardrobe. Cut with room to layer and finished with thoughtful details—it’s a dependable overshirt designed to earn its keep from the first frost through the last thaw.

Woven from a 12.5-oz. blend of organic cotton and wool, this herringbone fabric combines natural insulation with a soft, structured hand. The alternating yarns create a rich indigo-ash pattern with subtle depth, while the wool content helps regulate temperature through shifting conditions. Reinforced with double-needle felled construction for lasting durability, and designed to age gracefully with wear.
