Related: Carry-On Size Limits by Airline: Linear Inches, Explained
I spent six years working the gate at O'Hare. That means I have watched a few hundred thousand bags go down a belt and come back up looking worse than they went in, and it is where my standard for carry-on luggage for frequent flyers comes from. It has almost nothing to do with how a bag looks in a product photo.
Here is the short version of what decides it: bin fit, linear inches, wheelbase stability, handle wobble, and what the zipper does on the third trip. A case can be gorgeous and lose on all five. A plain case can win on all five and never get a second look from anyone.
The four bags below cover the four jobs people actually have. One hardside carry-on for the traveler who wants a shell and no decisions. One rolling duffel for gear and soft contents. One backpack for the person who refuses to check anything. And one checked spinner for the trips where 22 inches is a joke and you know it.
Best Overall Hardside: Traveler's Choice Pagosa 22-Inch Carry-On
The case for a hardshell is simple. Nothing inside gets crushed, the shell takes the abuse instead, and rain stops being a factor. The case against is just as simple. A shell has to absorb whatever the belt does to it, and the corners are where that shows up first. That is a real trade, not a marketing line.
What the Pagosa gives you is the shape most travelers actually want: a 22-inch carry-on class body, spinner wheels on all four corners, and an expandable zipper for the trip where you buy one thing too many. The four-wheel wheelbase is the part I care about most. A four-point base rolls beside you through a terminal instead of dragging behind you at an angle, and it takes the load off your wrist on the long walk to a far gate.
The expansion zipper is the one feature I would use rarely. Expand a carry-on before you reach the gate and you have just built a 22-inch bag that no longer fits the sizer. Expand it after you land, not before you board.
Best for Gear: Pacific Gear Duffel Bag with Rolling Wheels
A rolling duffel solves a problem a shell cannot. Soft contents, bulky contents, and weird-shaped contents all go in without a packing puzzle, and the whole bag squishes when it needs to. That last part matters more than people think. A soft bag is the easiest thing in the world to gate check, because it will always find a corner of space in a full bin.
What you give up is protection. There is no shell here, so anything fragile needs to be wrapped and anything crushable should not ride on the bottom. A duffel also carries differently. Packed full and heavy, the load sits lower and further back than a spinner does, and the wheels take more punishment on curbs and stairs.
For sports gear, boots, laundry, or a road trip where the bag lives in a trunk, this is the shape that makes sense. For a business trip with a laptop and a pressed shirt, it is the wrong tool and you already know it.
Best Carry-On Backpack: MATEIN Extra Large Expandable Travel Backpack
Backpacks win on stairs, trains, cobblestones, and the walk from the curb. They lose on bin fit, and they lose badly, because a fully packed backpack is deeper than a spinner of the same capacity. Depth is what the sizer measures, and depth is exactly what a stuffed backpack adds.
So the rule with any carry-on backpack is to measure it packed, not empty, and to treat the expansion zipper as a checked-bag feature rather than a carry-on feature. Expand it and you are probably buying a gate check.
The MATEIN is built for the one-bag traveler: a large main compartment, a separate laptop area, and enough structure that it holds its shape when you set it down. If you are the person who would rather walk past the baggage claim than wait at it, this is the category to be in. Just know you are trading the wheelbase for your own shoulders.
Best Checked Bag: Travelpro Maxlite 5 Softside 25-Inch Spinner
Travelpro is the brand the crews carry, and the Maxlite line is the reason. It is softside, which means it gives when the pile shifts in the hold, and it is built for the person who checks a bag every week and does not want to think about it again.
The 25-inch size class is a checked bag. It is not a carry-on, it will not fit a bin, and if you buy it expecting to walk it on, you will be gate checking it on the first flight. What it is for is the trip where 22 inches is genuinely not enough: cold weather, a full week of work, or two people sharing one case.
Red is the practical choice, and I will defend that to the end. A bright bag is the fastest thing to spot on a moving carousel, and color is the one feature that never fails. Softside also means the zippers are doing more work, so the zipper pull and the lining are the two things to check on any soft bag.
How I judge a bag
My checklist is the one I used at the gate, and none of it requires a lab.
Measure linear inches yourself. Length plus width plus height, including the wheels and the handle. The number on the listing is often the body only, which is how a case advertised at 21 inches measures 23 on a tape. Every airline sizer measures the outside of the bag, not the inside.
Check the wheelbase. Four spinner wheels should sit flat on tile with no rocking. Two inline wheels should track straight when you pull the bag behind you at speed. Rocking or veering means the housing is loose, and a loose housing is the beginning of the end.
Wobble the handle at full extension. If it moves side to side before the bag has ever been on a belt, it will be worse after twenty flights.
Open and close the zipper with the bag empty, then with the bag full. A zipper that catches the liner when the bag is empty will catch it worse when the bag is stuffed. Zippers are the first thing to die, the handle is the second, and both are decided before you ever leave the house.
Weigh the empty case against your weight limit. That is the contract. A 9-pound case eats 9 pounds of your 50, and no amount of clever packing gets those pounds back.
What the specs actually tell you
Hardside versus softside is not a quality question, it is a contents question. A shell protects what is inside and passes the damage along to itself. A soft bag absorbs the hit and passes some of it inward. If you pack electronics, bottles, or anything that dents, hardside earns its keep. If you pack clothes and shoes, softside packs easier, weighs less, and squishes into a bin that is already half full.
Spinner wheels versus inline wheels is a walking question. Four spinners are easier on your wrist and worse on rough ground, because small wheels catch on grates and cobblestones. Two inline wheels roll better over bad pavement and tip over if you let go on a slope. Airports are smooth, cities are not.
Expansion zippers are a trap in carry-on sizes and a gift in checked sizes. In a carry-on, expanding the bag is how you lose bin fit. In a checked bag, it is how you get home with the extra things you bought.
Size class is the decision that matters most, and it is the one people rush. A 22-inch carry-on class bag is the largest thing most airlines will let you walk on with. A 25-inch bag is checked, full stop. Buying bigger than you need is how a carry-on trip turns into a baggage claim trip, and checked bags are the ones that get lost.

Carry-on or checked?
Buy the smallest bag that holds your trip, not the largest bag you can afford. Carry-on class keeps you out of the baggage claim line, out of the lost bag queue, and out of the argument at the gate. Checked sizes are for the trips where you have already decided you are not carrying it all.
Which one for a one-bag trip?
The MATEIN backpack if you will be on trains, stairs, or uneven streets. The Traveler's Choice Pagosa if your trip is a direct flight and a hotel elevator. The Pacific Gear duffel if half your contents are gear rather than clothes. None of them is wrong, but only one of them fits the way you actually move.
Should you buy the Traveler's Choice Pagosa?
Yes, if you want a shell and you want to stop thinking about your bag. A 22-inch carry-on class hardside with four spinner wheels is the default answer for most domestic flying, and this is a clean version of that answer. The expansion zipper is there for the return leg, when you have already cleared security and the bin is behind you.
Skip it if you pack fragile-free clothes only and want the lightest possible thing on your shoulder. Softside wins that argument. But if you have ever opened a bag to find a cracked bottle or a crushed box, hardside is the fix.
Should you buy the Pacific Gear rolling duffel?
Yes, if your contents are soft and your trips are not about looking sharp. Gear, boots, laundry, ski layers, and anything with an awkward shape all go in without a fight, and a soft duffel is the bag you want when the gate announces a full flight and asks for volunteers to check. It will fit.
No, if you are carrying a laptop, a camera, or anything that needs a shell around it. And no if you like a bag that stands up on its own in a hotel room, because a packed duffel does not always cooperate.
Should you buy the MATEIN carry-on backpack?
Yes, if you are serious about one-bag travel. It holds more than it looks like it holds, it keeps your hands free, and it survives the parts of a trip that happen outside the airport, which is most of them. That is the whole argument for a backpack over a spinner.
No, if you are the traveler who packs to the limit and then tries to walk it on. A stuffed backpack is deep, depth is what the sizer measures, and the gate agent is not going to negotiate. Pack it, measure it, and leave the expansion zipper alone until you are checking it.
Should you buy the Travelpro Maxlite 5 25-inch?
Yes, if you check a bag often enough that you have stopped wanting to think about it. Travelpro is the crew brand for a reason, the softside shell gives when the pile shifts, and 25 inches is the honest size for a cold weather trip or a full week of work. Red is the right color, because you will spot it on the carousel from twenty feet away.
No, if you are trying to avoid the baggage claim entirely. This is not a carry-on, and treating it like one means a gate check on every flight. Buy it for the trips where you have already accepted the checked bag reality, not for the trips where you have not.
