Mous’s first hardshell suitcase is a 55 × 40 × 20 cm carry-on made with the company’s UltraMatrix polypropylene composite. The listed case weighs 2.8 kg without its removable compression pad, holds 36 litres in its main compartment plus a 1.2-litre external pocket, and was listed at US$499.99 on Mous’s product page when checked in 2026. Its durability advantage is a Mous claim, not an independently verified comparison.
What Mous is selling
The Optimal Hardshell Carry-On Suitcase marks Mous’s move from protective phone cases into hardshell cabin luggage. The product combines a woven composite shell with travel features such as replaceable components, an integrated combination lock and an AirTag sleeve. The listed price was US$499.99 on Mous’s product page when checked in 2026; price and regional availability can change, so confirm the current regional listing before buying.
Will it fit in the overhead bin?
Mous lists the carry-on at 55 × 40 × 20 cm and says this format meets most major airline standards. That does not guarantee acceptance on every airline or fare: cabin baggage limits vary, and an airline may apply different rules to particular routes or tickets. Check the dimensions and weight allowance for your specific flight before travelling.
How much can you pack?
Mous lists 36 litres for the main compartment and a further 1.2 litres for the external pocket. The case weighs 2.8 kg without the removable compression pad and 2.9 kg with it, so include the case’s weight when estimating what you can take under an airline’s cabin-bag limit.

#1 Best Overall
- The Perfect Size: The textured, scratch-resistant exterior of this hardshell carry-on luggage is 15 x 10 x 23 inches" with wheels and meets the cabin size restrictions of most airlines.
- Stay Organized: This small hard-sided carry-on suitcase provides ample packing room with a spacious 20.5" x 14.5" x 10.0" interior. The elastic straps, divider, and pouch ensure everything stays neatly in place
Mous says the case works with its Optimal document, toiletry and tech pouches. Its Optimal Compression Wardrobe is too large to fit as intended, so the compatible pouch system is not a guarantee that every Optimal organizer will fit.
What is the shell made of, and how strong is it?
Mous calls the shell UltraMatrix, describing it as a self-reinforced polypropylene composite whose fibres are woven and fused into the shell. The company says it is up to six times more impact-resistant than standard polycarbonate. That figure is Mous’s manufacturer claim; the sources reviewed do not provide independent comparative test results to verify it.

- Dedicated Front-Access Laptop Compartment for Effortless Travel: Dedicated front compartment (14.5" x 10" x 1") fits laptops up to 16 inches, with pockets for pens and essentials. Best for slim laptops without bulky cases or sleeves. Gaming laptops may not fit. Stay organized with upright access to your computer—without opening the main compartment or unpacking your luggage. Ideal for airport security and business travel.
- Reinforced Aluminum Frame Protection System for Durable Travel: Built for frequent travel with a reinforced aluminum frame, 3-layer polycarbonate shell, and reinforced corner protectors. The rigid frame supports the case opening, while the impact-resistant shell and reinforced corners help protect your belongings from everyday bumps, drops, and handling during travel.
- Effortless All-in-One Zipperless Carry-On System for Easy Access: Open your suitcase without dealing with a zipper. Dual TSA-approved combination locks secure the main compartment and allow quick, direct access with a simple press. The zipperless construction makes packing, unpacking, and retrieving essentials faster and easier at the airport, hotel, or on the go.
- Built-In Travel Convenience Features for On-the-Go Use: Designed for more than just packing. A one-touch hidden cup holder keeps your drink within reach, while the integrated bag hook provides a convenient place for small bags and personal items. The flat top surface also offers a handy spot to place a laptop or other essentials when you need both hands free.
- Shock-Absorbing, Quiet & Removable Wheels for Smooth Mobility: Four 360° spinner wheels combine shock absorption with quiet rolling to help smooth out bumps and uneven surfaces. Each wheel is individually removable with a simple press for easier cleaning, maintenance, or replacement—so you can keep your suitcase rolling smoothly for longer.
Which travel features are included?
- Wheels: Hinomoto wheels.
- Zips: YKK RCW zips.
- Lock: TSA-approved combination lock.
- Tracker storage: a hidden sleeve for an AirTag.
- Replaceable parts: Mous lists the wheels, handle, lock and badge as replaceable components.
Replaceable components may make repair more practical than replacing the whole case, but the listing alone does not establish repair costs, parts availability or how quickly repairs can be completed. Check those details with Mous if they matter to your purchase.
What does the warranty cover?
Mous describes a 25-year limited lifetime warranty covering manufacturing defects or faults under normal use. The scope depends on the warranty’s terms and conditions, so read the full Mous warranty terms before relying on that coverage.

How does it compare with Mous’s medium suitcase?
The medium hardshell is a checked-baggage option, not a larger cabin case. Mous lists its dimensions as 675 × 460 × 289 mm and estimates capacity at about 73 litres, while noting on the page reviewed that the exact capacity remained subject to final sign-off. Checked-bag size and weight limits also vary by airline.
| Model | Intended use | Dimensions | Capacity | Weight |
|---|---|---|---|---|
| Optimal Hardshell Carry-On | Cabin baggage; airline rules vary | 55 × 40 × 20 cm | 36 L main compartment plus 1.2 L external pocket | 2.8 kg without compression pad; 2.9 kg with it |
| Medium Hardshell Suitcase | Checked baggage | 675 × 460 × 289 mm | About 73 L, estimated by Mous; exact capacity was awaiting final sign-off on the page reviewed | Not stated on the Mous product page reviewed |

What to weigh before buying
For a purchase decision, compare the case’s actual external dimensions and empty weight with your airline’s allowance, then consider whether the capacity and organization suit your trip. The composite construction, replaceable parts and warranty are relevant features, but Mous’s impact-resistance comparison should be treated as a manufacturer claim rather than an independently established result. The listed US$499.99 price is a snapshot, not a guaranteed current price.
