Gonex Expandable Packing Cubes, $13 with code AY9S85YS

You already know that packing cubes can make traveling slightly less terrible (though they won’t stop United from beating your ass), but Gonex’s take on the product category includes a second zipper and extra material, allowing them to expand while you’re packing, and compress when it’s time to stuff everything in to your carry-on. For a limited time, get a set of three in the color of your choice for $13 with promo code AY9S85YS.
