How this works
Simulating a traveler's dilemma fifty times.
We asked one AI model the questions real luggage shoppers would ask: What's the best luggage? I'm about to buy — what should I get? What's the most durable? What are the top brands? If you were buying for me, what would you choose? We didn't pick the durability one — we asked the model first what it leads with when someone wants luggage, three times, cold, and it said durability every time.
Fifty separate conversations, each starting from nothing, so no answer could crib from another. Half asked about luggage, half about carry-ons. No browsing, no memory, no follow-ups — the model answering from what it has already read about this category, which is the picture that persists between now and whenever someone asks it again.
Then we counted three things: who gets named, who gets named first, and how hard the answer pushes.
Then we checked all of it against two things outside the model. What the brands say on their own warranty pages and product listings. And how many distinct wheeled designs each one actually sells.
Those two together separate a brand nobody has heard of from a brand that is simply small. A four-suitcase brand named in every answer and a hundred-suitcase brand named in none are very different stories, and the answers alone cannot tell you which one you are looking at.

A word on the word.
The clarity gap for luggage falls in the same quadrant as both regional banks and women's deodorant. But there is a new split inside that quadrant, because one word was covering two opposite situations — hence Blurry rather than Unsettled.
When you ask about luggage, you don't get a conversation about suitcases. You get a conversation about warranties. Nearly every answer landed in the same place: the bag will die at the wheels, the handle or the zipper, so the only question worth asking is who pays when it does. That is the argument this category has settled into, and it means a brand's fine print now decides its standing more than the headlines on ads.
Which is also why the answer changes depending on how you ask. Asked which brands are top, the same two names came back first and second every single time — the expensive, famous ones you know. Asked what to actually buy, a lower cost brand led every time, and the famous names slid down the page. Both answers have total confidence and they perfectly contradict each other.

The Read
This is not your grandpa's suitcase category. The explosion of brands makes for a strange combination of realities. The same seven names come back every time, which reads as consensus until you notice that changing the question changes the winner entirely — ask what the top brands are and you get Rimowa, ask what to actually buy and you get Travelpro, and both answers are delivered with total confidence.
Luggage also seems to be a category about replacements and repairs as much as first purchases. What should worry any suitcase brand is the Away finding. Not only is the warranty the key, but even after Away did the work and changed the policy, the recommendation still comes back citing the old terms, which can't be fixed by marketing spend.

The Standings
There is no single winner on this page, and that is the finding rather than a flaw in it. This category answers a different brand depending on what you ask, so the table below is one answer among four:
— Asked what the top brands are: Rimowa, first in all five runs.
— Asked what to actually buy: Travelpro, first in all five.
— Backed hardest across all 25 runs, which is what the table below measures: Briggs & Riley.
— Furthest above what it actually sells, which is what the gap chart further down measures: Monos.
The table and the gap chart are not two versions of the same league. The table asks how strongly the answers back a brand; the gap asks whether that backing matches how much of the category the brand really accounts for. A brand can be high in one and low in the other, and several here are.
Brands are grouped rather than ranked, because the runs cannot separate all of them. Briggs & Riley sits on its own at the top and stayed there in every test we ran. Below it the gaps close fast — on the strictest reading, six of these ten brands are not distinguishable from one another at all. Where two brands share a line, that is the honest answer rather than a tie we could not be bothered to break.

Presence, Rank and the Index come from the 25 primary-noun runs. Absence is counted across all 50 runs, both nouns. Conviction is scored on 24 of the 25 primary-noun runs — one run's full text was lost, so it carries no score rather than a guessed one.
Two baggage brands are worth stopping the conveyor belt for: Rimowa comes up in all 25 primary-noun runs and is talked out of in most of them — some version of “buy it because you want it, not because it performs better” appears again and again. It has the weakest backing of any brand that gets named every time. Away is named just as often and sits eighth of ten, because what is said about it is wrong; that is the finding below. Calpak, Delsey, Level8 get named often enough to qualify, but nothing checkable was ever said about them — no claim about materials, warranty, or who makes them. With nothing to verify, they are left out of the table rather than guessed at.

The Signal
The Lag · this week's featured finding
Away changed its warranty on 14 April 2026. The answers still describe the old one, and use it as the reason to recommend a competitor.
The recommendation logic in this category is a single sentence, and it appeared in roughly four out of five runs: buy Briggs & Riley, because its warranty covers airline damage and the newer brands' warranties do not.
The first half is true, and checkable on Briggs & Riley's own page: “we will be happy to repair your luggage at no charge”, for life, with no proof of purchase required.
The second half is false. Away's own page reads “Away LifetimeCare covers airline mishandling when it results in functional damage to your suitcase”, and lists airline and baggage mishandling as covered. That coverage began on 14 April 2026. July's terms exclude improper use and cosmetic damage and say nothing about airline handling at all. Only Monos partly supports the claim, and only because its airline-damage cover sits in a paid tier rather than the base warranty.
So a brand made a real, dated, published change to the exact term it was being marked down for, and four months later the answers still recommend against it on the superseded version. The Lag enters the signal deck for this: a brand changed a verifiable fact about itself, the change is public and dated, and the recommendation still runs on the old one.
Two smaller failures sit underneath it. Zero Halliburton is described as predating Rimowa's aluminium cases; both companies' own records say otherwise — Rimowa 1937, Zero Halliburton 1938. And Monos is credited with Hinomoto wheels in run after run, while Monos states plainly that it designs its own.

Method
The Battery
The same five questions every week, in the same words, run five times each in clean independent contexts with no history, no tools and no web access. Only the category noun changes week to week.Primary noun luggage
Adjacent noun carry-on — because people don't all shop with the same vocabulary, and the answers move when the word does.
Measured 11 August 2026 — the 50-run battery. Published 14 August 2026. A category's answers can move between the run and the Friday, so both dates are stated and the number is read against the day it was taken.
The reality check
To know whether a ranking matches the real market you need something real to hold it against. A regulated category has filings for that. Luggage has no such list, so we counted what each brand actually sells: every distinct wheeled design on its own website, colours collapsed, counted the same way for everyone. That count is the brand's catalogue wherever this page uses the word.The gap is measured in percentile points. Both lists are laid out from 0 to 100 — what the catalogue says, and what the answers say. The gap is how far apart a brand sits on the two. Fifty points is half the category.
The count doesn't care whether a brand sells through department stores or only online — which is the whole point, because the interesting brands here deliberately do one and not the other.
What we threw out
Shipping records, first and hardest. The same company files under several different names at customs, and one brand came back as either 81 shipments or 1,274 depending on which database you asked. A number that unstable cannot anchor a ranking, so it is not in this edition.Two brands are named on this page but missing from the count: Calpak's site blocks it, and Paravel's wouldn't answer.
The range
Every figure here carries one. The 25 primary-noun conversations are a sample and not a census, and the interval printed beside each number is where it sits if those 25 are drawn again.Across all 50 runs, both nouns, the answers named 36 brands between them. Six that will sell an American a wheeled cabin case today were never named once: MVST, NOBL, Sterling Pacific, LUGGEX, Solgaard and Carl Friedrik. Level8 came up five times. Roam twice. Arlo Skye and Paravel once each.
One we missed. Quince sells wheeled carry-ons under its own name from a US storefront, so it meets the rule below and belongs in the set. We built the set without it. It was named in none of the 50 runs, so no ranking here moves. But the count it is measured against was drawn one brand short, and we would rather say so than let a reader find it. Quince is in the set from the next luggage run.
We chase one absence properly each week, and this week it was MVST — an aluminium case sold as the affordable Rimowa. Asked straight out whether MVST is a luggage brand, the answer says yes, three times out of three, and describes it in confident detail. The detail is wrong. It names product lines MVST doesn't sell and a material it doesn't use. Then, asked for a good aluminium case costing far less than a Rimowa — which is MVST's own sales pitch almost word for word — MVST doesn't come up once, while five other brands do.
The interesting version of that: a brand the answers know, describe in confident and partly wrong detail, and then decline to name for the exact pitch it sells on. The dull version: MVST is too small to have registered, and it has no US import record under any name we could find.
The dull one survives, so we are not claiming the first. Naming the hypothesis we killed is the point — an absence only means something once the boring reason for it has been ruled out.

Who is in this category, and on whose authority
What countsA brand selling a wheeled cabin case — a structured case with wheels and a pull-out handle — under its own name.
Sold whereTo a US shopper, through any channel, from a storefront you can reach from the United States. Direct sellers and department-store brands count the same.
As of11 August 2026.
What is excluded, namedBackpacks, duffels and packing gear — Osprey, Patagonia, Eagle Creek, Tortuga, Cotopaxi, Bellroy, Red Oxx, Tom Bihn, Filson, Thule. Equipment cases: Pelican. Peak Design, which does sell a roller but is named for its backpack in almost every mention. Retailer own-label: Amazon Basics. Contract factories that sell under no name of their own.
Every other category we have measured had a regulator or a trade body publishing the list of who belongs. Luggage has neither. So this list is ours, and we would rather say that than borrow an authority that does not cover the category. What saves it: you can check any single name yourself in about a minute, on that brand's own website.
A ranking only means something if the brands qualified before anyone saw a score. This rule was written and published before the first run.
Scores are not comparable across categories, and no edition cites
