There's an art to packing a carry-on bag: everything has to be accessible, organized, and serve a purpose. As a carry-on-only traveler, I'm big on packing my personal bag with intention and keeping my luggage as streamlined as possible; as such, there are a few tried-and-true products I always pack. Luckily, Amazon's stacked travel deals section always gives me a great excuse to stock up on those travel essentials that make all the difference.
