Hardside vs Softside Luggage (2026)
On official pages fetched November 10, 2026, Away describes hardside as an impact-resistant polycarbonate shell starting at $275, softside as abrasion- and water-resistant nylon starting at $225, and aluminum as a premium hard shell starting at $625. Monos, which sells polycarbonate and aluminum cases, not a softside line on the pages we fetched, says its German Makrolon polycarbonate flexes under impact and springs back. We compared those written material claims and the conflicting official measurements, not a drop-test scorecard. Confirm dimensions, including wheels, in an airline sizer.

Quick answer
On official pages fetched November 10, 2026, Away describes hardside as an impact-resistant polycarbonate shell starting at $275, softside as abrasion- and water-resistant nylon starting at $225, and aluminum as a premium hard shell starting at $625. We compared those written material claims and the conflicting official measurements, not a drop-test scorecard.
Last updated Prices checked Nov 10, 2026
We compared official Away luggage-materials and compare-materials pages, official Monos quality and luggage-buying-guide pages (the buying guide is dated August 31, 2026), and United’s official carry-on limit, all fetched November 10, 2026. We have not drop-tested these cases, and we do not invent scores. Away’s own official pages disagree with each other on some carry-on weights and dimensions; we disclose those conflicts instead of averaging them. Softside specifications in the table are Away’s, because that is the official softside line we fetched. Monos is cited for polycarbonate and aluminum claims only.

What official pages actually claim
| Hardside (polycarbonate) | Softside (nylon, Away) | Aluminum (hard shell) | |
|---|---|---|---|
| Starting price, official Away materials page | From $275 | From $225. Softside Carry-On listed at $225. | From $625 |
| What the shell is, as written | Away: “impact-resistant polycarbonate shell” and, on the compare page, a “durable, lightweight 100% polycarbonate hard shell” (ShockShield™). Monos: all of its luggage cases are vacuum-formed with German Makrolon polycarbonate that it calls lightweight, aerospace-grade, “nearly impossible to break,” and flexible enough to absorb impact and spring back. Those are Monos’s claims, not a test we ran. | Away: “abrasion and water-resistant flexible woven fabric,” with a light coating so spills wipe off, plus hidden exterior pockets (including a laptop pocket) and zipper expansion that Away says adds 15% more room when fully expanded. | Away: “premium anodized aluminum that absorbs impact,” designed to be sturdy; the case “will develop a character all its own.” Monos’s August 31, 2026 buying guide: aluminum is heavier and more structured, “dents rather than cracks,” and develops a patina. |
| Official Away carry-on weight (conflicts) | Luggage-materials page: 7.5 lb. Compare-materials page: Classic 8.6 lb (3.9 kg). Away’s own Carry-On product page, already cited in our Carry-On vs Carry-On Flex guide, also conflicts (Size block 7.5 lb vs header/meta 7.1 lb). We are not averaging these figures. | Luggage-materials page: 9.2 lb. Compare-materials page: 8.8 lb (4 kg). | Luggage-materials page lists 10.7 lb in one table and 10.5 lb in a later table on the same page. Compare-materials page: 10.5 lb (4.8 kg) for the Aluminum column. |
| Official Away carry-on dimensions (conflicts) | Luggage-materials: 21.7 × 14.4 × 9 in. Compare-materials Classic: 22.1 × 14.5 × 9.1 in. The Carry-On product Size block used elsewhere on this site is 22 × 14.4 × 9.1 in including wheels and handles, with a same-page FAQ of 21.7 × 14.4 × 9 in. | Luggage-materials: 21.9 × 15 × 9.1 in. Compare-materials: 22.2 × 14.4 × 9.1 in, plus 2.25 in of depth when expanded. A 15 in official width is over United’s 14 in limit (below). | Luggage-materials and compare-materials: 21.5 × 13.5 × 9 in. |
| Expansion, opening, lock | Away: Flex option expands 2.25 in (6 cm) on Flex carry-ons; 50/50 opening; TSA-accepted lock. Monos’s buying guide: an expanded carry-on may exceed airline limits, so keep expansion zipped away when flying if you use it. | Away: zipper expansion included on all Softside luggage; front-lid opening (one main packing compartment); TSA-accepted lock. | Away: no zipper expansion in the materials-page table; 50/50 opening; two TSA-approved combination locks on the Aluminum line; TSA-accepted lock listed in the comparison table. |
United’s official carry-on limit, fetched the same day, is 9 × 14 × 22 inches including handles and wheels. Several official Away widths sit at or over 14 inches (Classic 14.4 or 14.5 in, Softside 15 in on the materials page). That is why a sizer check matters more than a marketing “carry-on” label. See Away Carry-On vs Bigger Carry-On for the same airline rule applied to specific SKUs.
How to use those claims without inventing a winner
If you want a rigid shell and you accept scuffs, official polycarbonate pages are the match: Away’s hardside line from $275, and Monos’s Makrolon cases (Carry-On $275 USD on the quality page). If you want exterior pockets and built-in expansion, Away’s official softside pages — from $225, with a front-lid opening and a stated 15% expansion — describe that job. If you want a metal shell and you accept dents as patina, Away’s aluminum line from $625 and Monos’s aluminum buying-guide language describe that tradeoff, at a clearly higher official starting price and a higher official empty weight.
We are not declaring polycarbonate “unbreakable,” even though Monos uses that kind of language, and we are not declaring softside “always lighter.” On Away’s official pages, the softside carry-on is listed heavier than the hardside carry-on in both tables we fetched (9.2 vs 7.5 lb, or 8.8 vs 8.6 lb), despite the usual advice that fabric bags weigh less. Report the official numbers; do not generalize from one brand’s line to every suitcase in a store aisle.
Warranty is a separate decision. Away’s materials pages repeat LifetimeCare language: complimentary repairs for the first five years for manufacturing defects and travel damage such as airline mishandling, one replacement if unrepairable in that window, and repairs for the life of the suitcase with shipping covered. Monos’s buying guide, dated August 31, 2026, describes a limited lifetime warranty on wheels, handles, locks, zippers, and functional shell damage, with optional Lifetime Warranty+ add-ons for airline damage and lost luggage. Read the live warranty page for the case you buy; those programs are not identical. Our Away vs Monos comparison covers the warranty split in more detail.
Who should skip this guide
- Readers choosing between two named hardside models. Use Away vs Monos, Away vs July, or Monos vs NOBL.
- Shoppers who want a single “best suitcase” score. We do not invent scores, and official Away measurements conflict with each other.
- People comparing a weekender duffel with a carry-on spinner. That is a different question; the weekender-vs-carry-on page is still in the holdback queue.
- Anyone who needs official softside specs from a brand other than Away. We did not fetch a second official softside materials table and will not invent one.

Travelpro vs Briggs & Riley (2026)
These are both official two-wheel, expandable 22-inch softside carry-ons, not spinner-to-spinner twins. Travelpro’s Platinum Elite Carry-On Rollaboard is $390, 7.7 lb and 53.5 L, with overall dimensions of 23 × 14.5 × 9 inches including wheels and handles — over United’s published 22 × 14 × 9 in box on height and width, though Travelpro says it is sizer-bin tested. Briggs & Riley’s Baseline Essential 22" is $679, 9.7 lb and 39–51 L, with official unexpanded exterior dimensions of 22 × 14 × 9 inches. The warranty split is sharper than the size split.
guideWeekender vs Carry-On (2026)
Choose a weekender duffel if you want a lighter soft bag you can shoulder or stack on a roller — Away’s Weekender is $248, 38 L, and 3.8 lb with the strap, but Away’s own FAQ says it is not a personal item and is too large under a seat when fully packed. Choose a wheeled carry-on if you want a structured spinner with a built-in lock and a suitcase warranty; Away’s Carry-On is $275 and about twice the empty weight, with official size figures that conflict across Away’s own pages. Confirm the packed bag in a sizer. United’s published limit is 9 × 14 × 22 inches including handles and wheels.
guideTSA-Accepted Luggage Locks, Explained (2026)
A TSA-accepted lock is one that U.S. screening officers can open with a master key, inspect, and relock, so they may not have to cut it. Official TSA language names two systems — Travel Sentry and Safe Skies — and also says TSA has no position on these locks as a security measure and will still remove them if necessary. Look for the Travel Sentry Red Diamond (and a code such as TSA007) or the Safe Skies mark on the lock itself, not only on the box. This is not a theft-proofing guarantee, and we are not ranking a “best” lock we have not tested.
best ofThe Best Carry-On Luggage for Holiday Travel
If you need a bag that matches United’s published 9 × 14 × 22 in limit (wheels and handle included), Monos’ official Carry-On dimensions do. Travelpro’s Maxlite 5 is much lighter and cheaper, and Away’s The Carry-On sits slightly over that published box on two dimensions — confirm with a sizer.
comparisonAway vs Monos Carry-On (2026)
Both list at $275. Monos publishes overall dimensions that match United’s 9 × 14 × 22 in box and is lighter. Away’s Size block is slightly larger, and its included LifetimeCare covers functional airline mishandling for five years — something Monos’ included warranty does not.
comparisonAway vs July Carry-On (2026)
Away’s official list price is $275. July’s Carry On lists at $295 and was on sale for $236 (20% off) on November 10, 2026. The sharper split is warranty and extras: Away’s included LifetimeCare covers functional airline mishandling in years 1–5; July’s limited lifetime warranty covers manufacturing defects, and the bag includes an ejectable USB-C battery and a built-in tracker. Both official widths sit over United’s published 14 in limit.
comparisonMonos vs NOBL Carry-On (2026)
Monos lists the Carry-On at $275, 6.60 lb, and 22 × 14 × 9 in including wheels and handles — a published match for United’s 9 × 14 × 22 in box. NOBL’s All-in-One was $289 on November 10, 2026, and includes a front laptop pocket, cup holder, USB ports and a tracker, but its official pages disagree on exterior size, weight and liters, and they say those measurements do not include wheels. We compared the written pages, not a sizer test of our own.
comparisonAway Carry-On vs Carry-On Flex (2026)
These are the same Away carry-on family with one official difference that matters: the Flex adds a wraparound zipper that expands 2.25 in (6 cm), taking capacity from 41 L to 47 L. It costs $325 against $275 for the non-expandable Carry-On, and it weighs 7.9 lb against 7.5 lb. Away’s own Flex FAQ says the unexpanded bag is the internationally compliant size and that you may need to check it when it is fully expanded.
