This expandable duffel bag can be every bag you might need. The convertible design grows from a day to weekend size, and then once more to suit longer trips. It can be worn three ways, too—on the shoulder, cross-body, or as a backpack. An adjustable cinch system is how this bag can grow and shrink. It can handle up to 90 pounds and is durably made to keep up with you, wherever you take it.
