Los Angeles-based photographer Jason Travis has spent the past few years documenting a variety of people and the contents of their bags in his Persona series. For our very own curated Roam Fellow Traveler series, Travis goes even more granular, shooting travelers and their carry-on bag contents to see what essential items they can't leave home without.
