Are you an over-packer? or do you find yourself always coming home with more than you brought on your trips? If so, the A. Saks Expandable Collection is just for you. Each bag has an expansion zipper that extends the bag for extra capacity when you needed it making room for all the gifts you bring home or those extra catalogs you acquired at your last business meeting. Choose from bags made of Rip-stop nylon keeping things light and durable, or choose from Ballistic Nylon for the extra durability and heavier loads.
