Totes are one of the most essential travel items you can own—the best tote bags are endlessly versatile and tend to have room for everything you could need while in transit. For some travelers, a sturdy leather tote is a no-brainer personal item for flights: It's bigger than most purses, so you can more easily fit a laptop, water bottle, and all other plane accessories inside. For others, an easy-to-fold cotton option might be the item you break out mid-trip for a visit to the beach or farmers market.
