What Our Gearhead(R) Experts Are Saying:"I packed a week of rolled shirts and socks into the small and medium set for a carry-on-only trip, and the compression zippers flattened everything down enough to fit an extra pair of shoes. The semitransparent fabric made it easy to find what I needed without unzipping every cube."A carry-on-only trip always comes down to a game of inches, and the Compression Packing Cube from Thule is built to win that game. Roll your clothes, zip the cube shut, then pull the compression zipper closed and watch a full stack of shirts and socks flatten down into a fraction of the space it started in. Available in small, medium, or as a paired set, each cube uses durable ripstop nylon that shrugs off spills and daily wear, while semitransparent fabric lets you spot what's packed without digging through the whole bag. A webbing handle makes it simple to grab and hang once you've arrived, so unpacking is as easy as the pack-down was.
