A smart style with utilitarian origins, this shirt jacket takes its design cues — like clean lines, a button front and flap chest pockets — from our classic CPO Jackets, which themselves are based on a style issued to the U.S. Navy’s Chief Petty Officers (CPOs) in the 1930s. That military inspiration shows up in the fabric, too, an Italian cotton-linen with the look and feel of vintage fatigues. On the spectrum of shirt jackets, this falls firmly into the “sturdy shirt” category, both light enough to wear on its own and ready to layer. And did we mention there’s a matching Officer Cargo, too?
