The secret of this tote is a locking top zipper, with included keys, increasing security in crowded destinations. The tote is lightweight yet totally durable and, folded, fits in the included pouch. Or, for air travel, fill the pouch with your in-flight necessities (earbuds, tissues, phone; it fits nicely in most seatback pockets) and tuck the tote under your seat! Includes a sleeve that you can slip over your wheeled suitcase.
