23 Travel Essentials Our Editors Can't Fly Without

"This is weirdly specific, but I don't go anywhere without a travel bottle of dry shampoo. It's a lifesaver after long flights, red-eyes, delays, and cancellations, because at the very least, I don't feel completely gross no matter how long it's been since I've had a chance to wash my hair. When experiencing a major time zone change (like US to Europe), I like to hit the ground running and stay up in order to get on the new country's time. After a little bit of dry shampoo (or a lot), I feel more ready to start my adventure — even if it's sans shower." — Hilary White, editor, Smart Living and Love & Sex
