Sand stone and chambray blue both read as soft, worn-in colors, which is the right instinct for anything that has to survive a security line and a five-hour flight. The straight fit tech pant has enough room through the leg to sit for hours without cutting off circulation, and it doesn't hold a wrinkle no matter how you fold it into a bag. This is the outfit for the early flight where you're dressed before your brain is fully online, and it still looks fine by the time you're standing at baggage claim. Comfortable pants for travel shouldn't mean giving up on looking like an adult when you land.
Finish with tan suede sneakers and a woven leather watch strap.
