Navy Wool Twill CPO Jacket

Inspired by a World War II Chief Petty Officer shirt jacket, this full-fitting top-layer is cut from a brushed wool twill, and lined with a sleek nylon rip-stop stuffed with warm PrimaLoft® fill. There’s plenty of room in the shoulders, and a slight taper at the waist, so the silhouette balances its military heritage with a contemporary fit.

Love love the shirt!

Quality excellent


Fit excellent

Wanted one for myself but it’s sold out in women’s!

We spend our time in Jackson Hole and it’s the perfect thing to wear there!
