The Heritage Research CPO Deck Shirt is another example of how well the label can reference traditional cuts and make it there own. Inspired by the standard issue WWII USN shirt, the CPO Deck shirt features authentic 40′s scoop and envelope pockets, wide placket cuff, sideseam gusset inserts, double button strap collar and ID patch for name stencil. Seen here are three versions of the Heritage Research CPO Deck Shirt with raw denim, chambray blue and oatmeal.

Thanks to Oi Polloi for the info.
