The latest from online luggage purveyor AWAY is the Expandables collection. As the name suggests, these travel bags can grow. Available in 4 smart sizes, they feature large, easy-access front-flap pockets, and wraparound zippers that allow the rolling cases to expand by 1.75 inches. That means you can pack in more souvenirs, more clothes, more whatever. Choose from 37, 47, 73, & 106 liter sizes.
