Whether its a college student returning back to school, a family camping trip, or a weekend vacation, it is a highly versatile bag that functions for a diversity of trips. This duffel has the ability to expand into a roomy rolling duffel which then collapses and folds flat into a small bag when not in use for easy storage, a feature that is well-appreciated by space-saving travelers.
