Navy and olive don't compete for attention, they just sit next to each other and look like they were always going to. The quarter-zip's ribbed knit layers clean under a jacket or on its own once the plane lands somewhere warmer, and the twill pant doesn't know the difference between an airport floor and eight hours in a middle seat. This is the uniform for the guy who'd rather spend his packing time on literally anything else.
Finish with suede desert boots and a canvas weekender bag.
