Rosamo RSM001 5-Piece Expandable Luggage Set, 22x14x9 Carry-On, TSA Lock

Expandable suitcases give you extra packing room when a trip calls for it, while the different case sizes help organize travel for one person or a family.

This five-piece Rosamo set pairs 20-, 24-, and 28-inch hard-shell suitcases with a duffel bag and toiletry pouch. The suitcases nest inside the 28-inch case for compact storage between trips.

Need a carry-on that fits the stated 22x14x9-inch dimensions? The 20-inch spinner is designed to meet that size, and its TSA lock adds a practical security feature for airport travel.

Fit and sizing

The set covers a range of trip lengths with three expandable suitcases: a 20-inch carry-on, a 24-inch medium case, and a 28-inch large case. All three have an expandable design, so you can adjust packing space to suit the trip. The carry-on measures 22x14x9 inches, including wheels and handles.

For a weekend away, the carry-on offers a compact choice, longer trips can call for the medium or large case. The accompanying water-resistant duffel has a trolley sleeve, and the toiletry pouch keeps small travel items together. When the set is not in use, the three suitcases nest inside the largest case to take up less closet space.

What stands out

The hard shells use ABS and polycarbonate, with a textured, scratch-resistant finish. Eight spinner wheels support rolling the cases through terminals, while the telescopic handle and top and side grab handles give you options for moving or lifting them. A built-in TSA combination lock is designed for travel security and inspection by airport authorities.

Inside, a zippered divider, three mesh pockets, and compression straps help separate clothing and keep belongings organized. Buyers often highlight the set’s appearance, range of sizes, and smooth rolling, feedback on zipper operation is mixed, with some finding the zippers smooth and others finding them harder to use.

When it makes sense

For family travel or a mix of short getaways and longer vacations, the expandable cases and nesting storage make the collection especially practical.
