Carry-on weight limits keep shrinking while overhead locker space gets more competitive. A suitcase that eats half your allowance before you pack a single item turns every trip into a negotiation between essentials and comfort.
How we choose
This roundup highlights eight hardshell cabin cases with empty weights at or under 3kg, spanning polypropylene and polycarbonate shells, expandable designs, and features like integrated USB charging. Each one solves a specific travel problem—whether that is staying under budget airline limits, adding packing room for the return leg, or keeping devices charged during long connections.

Samsonite S'Cure - Spinner, Black, S (55 cm - 34 L), Spinner
What it is
Samsonite S'Cure Spinner 55 is a 34-litre hardside cabin suitcase with an empty weight of 2.9kg and four double spinner wheels.
Why it's worth it
At 2.9kg, it leaves more of a cabin weight allowance for the contents, which suits solo travellers who lift their own case into an overhead locker. The three-point locking system closes securely, while the integrated TSA lock and ID tag are practical for trips where the case is out of reach. Samsonite states the Flowlite polypropylene shell keeps the weight down without giving up strength.
Caveat
At 55 x 40 x 20cm, it matches common cabin sizes, but some budget airlines enforce smaller hand-luggage limits, so check before flying.
American Tourister Soundbox, Yellow (Golden Yellow), Spinner S EXP (55 cm - 35.5/41 L), Soundbox
What it is
American Tourister Soundbox is an expandable polypropylene cabin spinner with double wheels and a recessed TSA lock.
Why it's worth it
American Tourister describes this as its first zipped polypropylene case with expandability, so you can create extra room when the shopping pile grows. The concentric circle design takes its cue from retro vinyl records, and the bright yellow shell is easy to spot. Double wheels are designed for smooth rolling, and the recessed TSA lock keeps the profile tidy. It is a good fit for travellers who want an expandable cabin case with more personality than basic black.
Caveat
The expanded setting adds packing room but may push the case past a strict airline sizer, so keep the expansion zips closed for low-cost flights.
Antler Single Stripe Hardside Carry-On Luggage, Black, 22x14x9, 40L
What it is
Antler Single Stripe Hardside Carry-On is a 40-litre polypropylene cabin suitcase with double spinner wheels and a TSA-approved lock.
Why it's worth it
At 5.7lb, it stays under the 3kg mark while using a polypropylene shell Antler says flexes under impact to resist cracking. Four double spinner wheels and a height-adjustable handle make one-handed steering realistic through station corridors. The TSA lock and recycled interior lining add everyday practicality. It is well suited to solo travellers who want a cabin shell with give rather than a rigid case.
Caveat
Antler notes the shell can pick up surface scuffs, so it may not be the right choice if you want the case to stay pristine.
Away The Carry-On Luggage, 22-inch Lightweight Hardside Spinner Suitcase
What it is
Away The Carry-On is a 22-inch hardside spinner suitcase with a 100% polycarbonate shell and 360-degree wheels.
Why it's worth it
Away fits its patented CompressMore dual-buckle panel into the 100% polycarbonate shell it describes as lightweight, so more can fit without repacking. The four WhisperGlide wheels are designed for smooth rolling through airport and station concourses, and the case's 21.7-inch height keeps it near typical overhead-bin limits. LifetimeCare Coverage adds repair support for the life of the case, which matters for a purchase at this price.
Caveat
The 22-inch case may be too tall for some European budget airline cabin policies, despite being sold as a carry-on.
DELSEY PARIS Helium Aero Hardside Expandable Luggage with Spinner Wheels, Brick Red, Carry-On Plus 21 Inch
What it is
Delsey Paris Helium Aero Carry-On Plus is a 21-inch hardside expandable suitcase with a polycarbonate shell and four double spinner wheels.
Why it's worth it
The Helium Aero expands by up to 2 inches, which is useful for the return leg without moving up to a bigger checked case. Delsey describes the shell as lightweight polycarbonate, and the recessed one-button locking handle is intended for stable maneuverability. Four double spinner wheels provide a wide rolling base, and the TSA-accepted lock is built in. It is a good fit for travellers who want a 21-inch carry-on that leaves a little extra packing room.
Caveat
This Carry-On Plus is sized for US-style limits, so check it against overseas airline sizers before relying on it as cabin luggage.
EASTPAK Resist'R Zip S - 34L Hardshell Suitcase with Dual Compartments, TSA Lock, Silent 360 Degree Spinner Wheels and Water-Resistant Design, Camo
What it is
Eastpak Resist'R Zip S is a 34-litre hardshell cabin suitcase with dual zippered compartments and 360-degree spinner wheels.
Why it's worth it
The two zippered compartments make it easy to keep items separate, which is handy when you need a change of clothes or documents at short notice. Eastpak says the Japanese-engineered spinner wheels are silent, and the 100% polycarbonate shell has a water-resistant finish. The soft-closing telescopic handle and reinforced bumpers add a bit of everyday durability. It is well suited to travellers who prefer organised internal sections in a compact cabin case.
Caveat
The Amazon listing does not quote an empty weight, so verify the current spec if you are strict about staying under 3kg.
Travelers Club Chicago Hardside Expandable Spinner Luggage, Teal, 22-Inch Carry-On
What it is
Travelers Club Chicago Hardside Expandable Spinner is a 22-inch ABS hardside carry-on with four multi-directional spinner wheels and a push-button telescopic handle.
Why it's worth it
This ABS hardside offers a simple, expandable design with four multi-directional spinner wheels and a push-button telescopic handle. It is priced well below many polycarbonate cases, making it an option for travellers who want a practical hardshell for a few trips a year. The expandable zipper gives a little more room for the way home, and the 22-inch size is positioned as a carry-on.
Caveat
It uses an ABS shell rather than polycarbonate, so travellers who want greater impact flexibility may prefer a different material.
Traveler's Choice Maxporter II Polycarbonate Hardside Trunk with Spinner Wheels, Green, 22-Inch Carry-on Luggage
What it is
Traveler's Choice Maxporter II is a 22-inch polycarbonate hardside trunk-style carry-on with spinner wheels and an integrated USB charging port.
Why it's worth it
The trunk-style opening and protective corner guards give it a different shape from clamshell cases, with more structured access to packing space. The T-Cruise handle and dual cyclone spherical spinner wheels are designed for stable rolling, and the integrated USB-C port lets you keep a phone charged while moving through the airport. It is a good fit for solo travellers who want a carry-on with built-in charging and extra corner protection.
Caveat
The USB charging port needs a separate power source, and the 22-inch trunk-style case may be slightly tall for some international cabin allowances.

How to choose the right lightweight hardshell suitcases under 3kg for easier carry-on travel
Takeaway
The right lightweight hardshell depends on where you fly, how you pack, and what you are willing to spend. These eight options cover the common trade-offs—material, expandability, organisation, and charging—so you can match the case to the trip rather than adjusting the trip to the case.
