Alpine green and charcoal sit close in tone, both muted enough to travel well without showing every wrinkle. The tee's soft against the skin and holds up through a long flight, and the jogger's brushed fabric with a drawstring waist beats sitting in stiff pants for hours. Picture a red-eye, shoes off under the seat, actually comfortable for once. It's a practical men's travel outfit for the flight where comfort matters more than looking buttoned-up.
Finish with gray slip-on sneakers and a canvas backpack.
