Khaki pulls warmth into a shirt that's mostly cool blue and white, and the relaxed fit gives you the most room of any pant here for a flight where comfort matters more than the crease. The check itself is small enough to read as texture from across an airport gate. This is the outfit for the long trip, the one with two connections and a time zone change your body won't forgive for a few days. A relaxed, comfortable men's travel outfit for the flights that actually earn the word long.

Finish with tan suede sneakers and a packable layer for the plane.
