Triple Aught Design Signal Field Shirt. Made in the USA of grey 100% wool fabric with black cotton overlays on shoulders and at collar and cuffs. Metal buttons down the front and at cuffs. Two large pockets on chest. Styled like a shirt, but the fabric is heavyweight wool, so would work as nice warm overshirt or jacket. Sized large, but design is somewhat fitted. Please see pictures for chest and length measurements. Excellent used condition.
