Best 3-Piece Luggage Sets: Top 9 Picks (October 2026)
The best 3 piece luggage sets include the Samsonite Omni PC 3-Piece Luggage Set for polycarbonate shells, the American Tourister Stratum 2.0 3-Piece Set for 1 in expansion, and the Rockland London 3-Piece Luggage Set for charcoal styling.
On this page (4 sections)
The Samsonite Omni PC 3-Piece Luggage Set is the strongest all-round pick here, with 20, 24 and 28 in cases, polycarbonate shells and a 10-year limited warranty. For ABS cases that all expand, consider American Tourister Stratum 2.0; for a softside set, look at American Tourister Pop Max.
A 3-piece set is useful when one carry-on cannot cover every trip. The medium and large cases can suit longer stays or shared packing, though three suitcases need more closet space than one or two.
Before choosing, compare the sizes you will use most, the shell material and where expansion is placed. Our luggage set size guide explains common case sizes, and the carry-on luggage buying guide covers what to check before taking the smallest case onboard.

How we chose these 3-piece luggage sets
We focused on sets with three cases and considered the details that help distinguish them: stated sizes, shell materials, expansion, interior layout and included locks. Warranty details were included where stated.
A size label does not guarantee that a carry-on fits every airline. Measure the case, including wheels and handles, and compare it with the airline's current limit; our guide to measuring carry-on luggage walks through that check.
The best 3-piece luggage sets by use
These nine options are ranked by score, with each badge pointing to a specific reason to choose that set. Read the case-size and expansion details closely, since those vary even among similar-looking sets.
Samsonite Omni PC 3-Piece Luggage Set: Best for polycarbonate shells
- 20, 24 and 28 in cases
- Polycarbonate shell
- Expandable design
- 10-year limited warranty
This set pairs a carry-on with medium and large checked cases. The polycarbonate shells, spinner wheels and TSA locks suit buyers who want those features across all three sizes.
Pros
- Three useful case sizes
- Polycarbonate construction
- 10-year limited warranty
Cons
- Hard shell may not suit travelers who prefer softside luggage
The Samsonite Omni PC set is the best fit if you want a polycarbonate shell across three common sizes. It includes a 20 in carry-on and 24 and 28 in spinner cases for checked luggage.
The micro-diamond texture is described as scratch-resistant, and the cases have side-mounted TSA locks. A mesh divider, cross straps and a zipped modesty pocket organize the main compartment.
Samsonite includes a 10-year limited warranty against defects in materials and workmanship. The brand says its products are tested to meet its standards; that is a manufacturer statement, not a claim of testing by Bedsit Journal.
Choose this set if the shell material and warranty matter more to you than matching expansion across all cases. Check the carry-on's full dimensions against your airline before flying.
American Tourister Stratum 2.0 3-Piece Set: Best for 1 in expansion
- Carry-on, medium and large cases
- ABS shell
- All cases expand 1 in
- Mesh door pocket and elastic tie tapes
All three ABS cases expand 1 in for extra packing room. The interior has a modesty pocket, mesh door pocket and elastic tie tapes.
Pros
- Expansion on all three cases
- Three interior organization features
- Adjustable trolley grip
Cons
- The set does not specify inch sizes for the medium and large cases
American Tourister Stratum 2.0 stands out because all three ABS cases expand 1 in. The set comes in carry-on, medium and large sizes, though exact inch dimensions for the medium and large cases are not specified here.
Inside, a modesty pocket, mesh door pocket and elastic tie tapes give you a few ways to separate clothing and small items. The trolley grip adjusts, and the wheels are described as wear-tested by the brand.
This is a practical pick if you want expansion across the set instead of only on the large suitcase. Confirm the exact case dimensions before buying, especially if you plan to use the smallest one as carry-on luggage.
Rockland London 3-Piece Luggage Set: Best for charcoal styling
- 20, 24 and 28 in cases
- ABS hard shell
- Expandable design
- Five-year warranty
The charcoal ABS set includes a carry-on and two checked sizes. Spinner wheels and mesh and elastic interior pockets cover the basics across the three cases.
Pros
- Three stated case sizes
- Expandable cases
- Five-year warranty
Cons
- The 20 in case measures 23 in tall including wheels
Rockland London gives you a 20, 24 and 28 in ABS set in charcoal. The cases expand and roll on multidirectional spinner wheels, with an aluminum telescoping handle.
The interior has mesh and zip pockets plus elastic pockets. Rockland states a five-year warranty, which is a useful point to compare with the coverage offered by other sets.
The stated carry-on dimensions are 23 x 9 x 14 in with wheels included. That height can exceed some airline limits, so measure the bag and check your route's rules before treating it as a cabin bag.
Rockland Melbourne 3-Piece Luggage Set: Best for black ABS cases
- 20, 24 and 28 in cases
- ABS hard shell
- Expandable design
- Five-year warranty
This black set offers the familiar carry-on, medium and large combination in ABS. The cases expand and have interior mesh and elastic pockets.
Pros
- Three stated case sizes
- Expandable design
- Five-year warranty
Cons
- The carry-on measures 23 in tall including wheels
Rockland Melbourne is a black ABS set with three cases in 20, 24 and 28 in sizes. Each case expands, and the interior includes mesh and elastic pockets for dividing clothes and small items.
The cases use spinner wheels and an aluminum telescoping handle. Rockland states a five-year warranty, matching the warranty period for the London set above.
The carry-on is stated as 23 in tall with wheels. Compare its full dimensions with your airline's size limit, since a nominal 20 in suitcase may measure taller once wheels are counted.
Coolife 3-Piece Lightweight Hardshell Set: Best for nested storage
- 20, 24 and 28 in cases
- ABS shell
- Cases nest for storage
- TSA-approved combination lock
The nested design saves closet space between trips. The set also has a TSA-approved combination lock, spinner wheels and an interior with mesh pockets and elastic straps.
Pros
- Nested cases save storage space
- TSA-approved combination lock
- Mesh pockets and elastic straps
Cons
- ABS shell may not suit buyers set on polycarbonate
The Coolife hardshell set is a useful option if closet space is tight because the smaller cases nest inside the large one. Its three ABS cases are identified as 20, 24 and 28 in sizes.
A TSA-approved combination lock, spinner wheels and telescoping handle cover common travel features. Inside, mesh zipper pockets and elastic straps help keep smaller items in place.
Choose this set when compact storage between trips matters. The nested arrangement means you can keep the full set together, though you'll still need room for the largest case.
American Tourister Pop Max 3-Piece Softside Set: Best for softside packing
- 21, 25 and 29 in cases
- Polyester softside construction
- Spinner wheels
- Three cases
The polyester cases are the softside option in this group. Their 21, 25 and 29 in sizes give buyers a different size range from the common 20, 24 and 28 in sets.
Pros
- Softside polyester construction
- Three stated case sizes
- Spinner wheels
Cons
- Interior organization details are limited
American Tourister Pop Max is the softside choice in this roundup. Its polyester cases measure 21, 25 and 29 in, a size range that differs from the 20, 24 and 28 in pattern used by several other sets here.
The four-wheel design is listed for each case. If you prefer fabric luggage over a firm shell, this set gives you that material choice in a three-size collection.
The available details provide little about interior pockets or expansion, so focus your comparison on the stated dimensions and softside construction. Check the full measurements before deciding whether the smallest case will work as carry-on luggage.
Coolife 3-Piece Set with TSA Lock: Best for a roomy expandable case
- 20, 24 and 28 in cases
- TSA-approved combination lock
- 28 in case expands by 15%
- YKK zippers
Only the 28 in case expands, adding 15% capacity; the 20 and 24 in cases do not expand. The set includes a TSA-approved lock and YKK zippers.
Pros
- Expansion on the large case
- TSA-approved combination lock
- YKK zippers
Cons
- Two smaller cases do not expand
This Coolife set puts its 15% expansion on the 28 in case. The 20 and 24 in cases do not expand, so it suits buyers who want extra room for checked luggage rather than more capacity in every case.
The set uses ABS and polycarbonate, with a TSA-approved combination lock and YKK zippers. Inside, cross-compression straps and a mesh pocket provide basic organization.
The capacity figures are 38 L for the 20 in case, 60 L for the 24 in case and 90 L for the expandable 28 in case. Pick it if you want a clear size-by-size capacity breakdown and expansion on the largest suitcase.
Coolife Hardside ABS 3-Piece Set: Best for a TSA lock on each case
- Small, medium and large cases
- ABS hard shell
- TSA combination lock
- Only the 28 in case expands
The set pairs three ABS cases with TSA combination locks and spinner wheels. The large case expands by 15%, while the small and medium cases do not.
Pros
- TSA combination lock
- Three case sizes
- Large case expands
Cons
- The 28 in case is the only expandable size
Coolife's ABS set includes a TSA combination lock and spinner wheels on a small, medium and large case. Only the 28 in case expands, adding 15% capacity; the smaller two stay at their standard size.
Compression straps and a divided interior help keep clothing in place. The manufacturer gives dimensions for all three cases, including wheels and carry handles, which makes airline and storage checks easier.
Choose it if expansion on the largest case is enough for your packing needs. If you expect to use the small case as carry-on, compare its full measurements with the airline's limit before packing.
Light Flight 3-Piece Luggage Set: Best for an expandable carry-on
- 20, 24 and 28 in cases
- ABS hard shell
- 20 in case expands by 25%
- TSA-approved combination lock
The 20 in carry-on expands by 25%, while the 24 and 28 in cases do not expand. This reverses the layout of sets that reserve expansion for the largest case.
Pros
- Expandable carry-on
- TSA-approved combination lock
- Interior pockets and compression straps
Cons
- Medium and large cases do not expand
Light Flight places its expansion on the 20 in carry-on, which expands by 25%. The 24 and 28 in cases do not expand, making this layout different from sets that add capacity to the largest case.
The ABS cases have spinner wheels and a TSA-approved combination lock. The interior includes a U-shaped zipper pocket, mesh pocket, small zippered pouch and compression straps.
Choose this set if you want added capacity in the smallest suitcase for trips when a personal item and carry-on are not enough. Check the 20 in case's full dimensions with your airline, especially after expansion.
What should you compare before buying a 3-piece set?
Compare actual case dimensions and expansion first, then look at shell material, interior layout and storage needs. A matching set can still have different features on the small, medium and large cases.
Which sizes will you use most?
A 20 in case is often sold as a carry-on, but full measurements matter more than the label. Wheels and handles add height, and airline limits vary; our carry-on size guide explains how to check.
The 24 and 28 in cases are typically aimed at checked luggage, but choose based on the space you need and your ability to lift and store the bags. Measure closet shelves and car trunks too, especially if you plan to keep all three cases together.
Where does each case expand?
Expansion can add useful room, but the placement differs. Stratum 2.0 expands all three cases by 1 in, while the Coolife TSA-lock set expands only its 28 in case and Light Flight expands only its 20 in case.
Look at the expansion detail for each size before choosing. If you mainly need extra room for souvenirs on longer trips, expansion on a checked case may fit; if you pack more in a carry-on, a set with a smaller expandable case could be more useful.
Which shell material suits your travel?
Most options here use ABS, while the Samsonite Omni PC uses polycarbonate and Pop Max uses polyester softside construction. Material is only one part of the decision, so consider the case layout and how you prefer to pack as well.
For a closer look at hard-shell materials, read our polycarbonate vs ABS luggage comparison. If you're deciding between fabric and hard shell, compare the space and organization features you want with the specific set.
Will three suitcases fit your home?
Three cases need more storage room than a single suitcase. Nested designs can reduce the footprint between trips, as with the Coolife lightweight set, but the largest case still determines how much space you need.
Consider where the set will live when it is not in use. If you travel with only one size most of the time, a 2-piece luggage set may be easier to store.
Which 3-piece luggage set should you choose?
Choose the Samsonite Omni PC if you want polycarbonate cases in three common sizes and a 10-year limited warranty. Pick Stratum 2.0 if expansion on all three ABS cases matters, Pop Max if you prefer softside luggage, or Light Flight if you want expansion on the carry-on.
Before ordering, verify each case's full dimensions and where it expands. For more options built around smaller bags, see our best carry-on luggage sets.

Frequently asked questions
What sizes usually come in a 3-piece luggage set?
Many 3-piece luggage sets pair a carry-on with medium and large suitcases, often around 20, 24 and 28 in. Sizes vary, so check each case's full dimensions, including wheels and handles, against your airline's rules and your storage space.
Our luggage set size guide explains what these common sizes can hold.
Is a 3-piece luggage set worth buying?
A 3-piece luggage set can make sense if you take trips of different lengths or share bags with family. You'll get more size options in one coordinated set, but you may have to store cases you rarely use.
Measure your closet and think about how often you check a bag before choosing three cases.
Should you choose hardside or softside luggage?
Choose hardside if you want a firm shell, and softside if you prefer fabric luggage. This roundup includes mostly ABS hard shells, one polycarbonate set and one polyester softside set.
Compare materials in our polycarbonate vs ABS luggage guide.
Do all cases in a luggage set expand?
No. Expansion varies by set and sometimes by case.
The American Tourister Stratum 2.0 says all three expand 1 in, while the Coolife set with TSA lock expands only its 28 in case.
Check which sizes expand if that feature matters for the way you pack.
Can you use the smallest suitcase as carry-on luggage?
Often, but the label alone does not confirm that a bag fits your flight. Measure its full outside dimensions and check the airline's current carry-on limit before travel.
See our carry-on size guide for the key measurements.
