Best lightweight carry-on luggage, by actual weight
Updated September 2026
Most "best lightweight luggage" lists rank by brand reputation, not a verified scale. Here's the same idea done the other way round: bags ordered by their actual published empty weight, so you can see exactly what you're trading off.
The lightest bags, by verified empty weight
| Bag | Empty weight | Shell |
|---|---|---|
| TravelPro Maxlite 5 (21″) | 5.5 lbs / 2.5 kg | Softside |
| Coolife Hardside Expandable (20″) | 5.7 lbs / 2.6 kg | Polypropylene, hardside |
| Kenneth Cole Reaction Out of Bounds (20″) | 6.2 lbs / 2.8 kg | Hardside |
| Amazon Basics Hardside Spinner (20″) | 6.6 lbs / 3.0 kg | Hardside |
| Samsonite Freeform Spinner | 6.6 lbs / 3.0 kg | Polypropylene, hardside |
| Away The Carry-On | 7.4 lbs / 3.4 kg | Polycarbonate, hardside |
Nearly 2 kg separates the lightest bag on this list from the heaviest — and that gap is entirely the suitcase's own weight, before you've packed anything.
Why empty weight actually matters
On US airlines, cabin bags usually aren't weighed — size is what gets checked. But most of Europe, the Middle East and Asia enforce a cabin-bag weight limit, and it applies to the bag and everything inside it. Emirates and Qatar Airways cap cabin bags at 7 kg; Lufthansa and SAS at 8 kg. A 3.4 kg empty suitcase leaves you under 4 kg for clothes, shoes and a laptop on those airlines — a 2.5 kg bag nearly doubles that. Run your own numbers with our carry-on checker, which covers both size and weight limits across 53 airlines.
The tradeoff: weight vs. durability
The lightest bags tend to be softside nylon or thinner polypropylene shells — they save weight but flex more and offer less protection for fragile items. Heavier polycarbonate shells, like Away's, prioritize rigidity and crush resistance over minimal weight. Neither is objectively "better" — it depends on whether you're optimizing for a strict weight-limited airline or for durability on rougher trips.
Bottom line
If you regularly fly weight-limited airlines, treat empty weight as a hard spec to check before you buy — not an afterthought. If you mostly fly US carriers that only enforce size, a heavier, more durable shell costs you nothing in practice. Either way, confirm the final fit against your specific airlines with the checker before you travel.
