Pack smart for short trips with the Protege collapsible travel duffel. Classified as a carry-on size, it works as a standalone bag for a weekend getaway or as a spare you can fold flat and tuck into your suitcase. Its standout feature is an end-to-end zip design that lets the bag compact down completely when it isn't in use, so it's easy to bring along for the trip out and fill with purchases or extras on the way home. Sized for 2-3 days of travel, it keeps your essentials sorted with a main compartment plus interior and exterior pockets, an interior pouch sized to hold a GPS tracker, an accessory pocket, and a trolley-handle sleeve with hidden pockets. An adjustable, detachable shoulder strap gives you a hands-friendly carry option, and the rear add-a-bag sleeve slides over most telescoping luggage handles so you can stack it on your roller bag.
