Away defined the $275–$350 premium carry-on category and Monos arrived to challenge them with slightly better materials, quieter wheels, and a design-forward aesthetic that resonated with younger travelers. Both use aerospace-grade polycarbonate shells, TSA-approved combination locks, and USB-A charging ports. The Away Bigger Carry-On ($365) is the roomier of Away's two primary carry-on sizes; the Monos Carry-On Pro ($295) is Monos's standard flagship. r/onebag travelers have tested both extensively and the consensus is closer than the marketing suggests.
Monos Carry-On Pro
The Monos Carry-On Pro wins on build quality details — quieter Hinomoto Japanese spinner wheels, a more robust handle mechanism, and materials that feel incrementally more premium. Away's handle wobble is a known issue reported by many long-term users. For travelers who use their carry-on every week, the Monos holds up better. For occasional travelers, Away's broader retail presence and lifetime warranty are genuine advantages.

Interior Volume and Packing
The Away Bigger Carry-On has approximately 47.9 liters of interior volume — a bit more than Away's standard Carry-On at 39.8 liters. The interior is split into two equal halves with a compression pad on one side and a laundry bag plus zipper divider on the other. The larger volume is the main reason to choose the Bigger over the standard — it handles a week-long trip without checked bags for most travelers.
The Monos Carry-On Pro at 40 liters is closer to Away's standard carry-on volume. The interior layout is similar — clamshell split with a compression zip and laundry bag. Monos's laundry bag is a slightly higher-quality material than Away's. Volume-wise, the Away Bigger is genuinely roomier. If packing capacity is your primary variable, Away wins.
Wheels and Handle
Monos uses Hinomoto Japanese spinner wheels — widely regarded as the best spinner wheels available on a production carry-on at this price point. They roll quietly, track straight on uneven airport tile, and don't collect debris. r/onebag users who've compared wheels directly consistently cite Monos's wheels as the most significant upgrade over Away.
Away's spinner wheels are serviceable but noticeably louder and less smooth than Monos. The bigger reported issue is Away's telescoping handle: multiple Away users on r/onebag and r/luggage report that the handle develops wobble after 1–2 years of regular use — a manufacturing quality issue that Away has not fully resolved across generations. Monos's handle mechanism feels more solid and maintains its rigidity over time.
Shell and Weight
Both use polycarbonate shells. Away's Bigger Carry-On weighs 8.1 lb — heavier than ideal. When airlines enforce a 15–17 lb carry-on weight limit, starting at 8.1 lb before packing leaves limited margin. Monos Carry-On Pro weighs 7.3 lb — lighter, and polycarbonate shell thickness is comparable.
Away's polycarbonate has a matte finish option (the popular Matte Black) that hides scratches well. Monos's finish is slightly glossier by default but available in a wider color range, including some particularly popular muted tones (Slate, Sprig, Desert Rose) that stand out on baggage carousels.
Charging and Warranty
Both carry-ons include a built-in USB-A charging port that connects to a removable battery (sold separately for Away; included as a portable charger with the Monos). The battery must be removed to check the bag — this is standard for lithium battery carry-on compliance, not a flaw in either design.
Away offers a lifetime warranty — they'll repair or replace the bag for free for defects or damage, no questions asked. This is a genuine differentiator and a reason many frequent travelers choose Away despite the handle issue. Monos offers a limited lifetime warranty that covers manufacturing defects but is slightly more conditional. Away's warranty is more straightforward.

FAQ
Does the Away Bigger Carry-On fit in overhead bins?
On most major US carriers (United, Delta, American) the Bigger Carry-On fits in standard overhead bins. On smaller regional jets (CRJ-700, E175), it may need to be gate-checked. The dimensions comply with most carry-on size limits, but the Bigger is at the upper edge.
Is Away's handle wobble covered under warranty?
Away's lifetime warranty should cover handle defects, and most users report success getting repairs or replacements. The process requires shipping the bag to Away — some users find this inconvenient. Monos will repair in-warranty defects as well.
Are these bags TSA-compliant for the lock?
Yes — both use TSA-approved combination locks with a master key provision that allows TSA agents to open and re-lock the bag during security screening without damaging the lock.
