White Driveline and space black sit on opposite ends of the warmth spectrum, and that's exactly why they work. The eye moves between them and stays interested. Technical fabric with a dry hand feel and real pockets. Boarding group 2. You didn't check a bag and you don't look like it. One less thing to think about at the airport. That's worth more than TSA Pre.
Finish with white minimalist sneakers and a dark nylon carry-on that fits overhead.
