UltraMatrix ® – Main shell
The core of the suitcase. UltraMatrix ® is a self-reinforced polypropylene composite, woven for strength, laminated for rigidity and engineered for low weight. It forms the high-performance shell that defines the suitcase’s durability and resilience.
ABS – External plastic components.
Used for durable, impact-resistant parts such as the wheel housings and trolley handle casing. ABS offers the toughness and lightness needed to withstand frequent knocks and rough handling.
Polycarbonate + ABS – Front badge bracket.
A blend of polycarbonate and ABS combines rigidity, scratch resistance and impact toughness to securely mount the front badge and maintain structural integrity.
Zinc – Front badge logo.
The Mous logo badge is made from zinc for its metallic strength, corrosion resistance and premium tactile finish – a subtle but durable design detail.
ABS – Internal plastic components.
Inside the suitcase, ABS is used for smaller structural parts like organisational frames and fixing elements, chosen for its toughness and dimensional stability.
Steel – Screws.
All fastening hardware is steel, ensuring strong, reliable fixing points for handles, wheels and internal components. Each suitcase includes spare screws to support repairability.
600D polyester – External pocket
The quick-access rear pocket is constructed from 600-denier polyester: a rugged, tightly woven fabric that stands up to daily wear and tear.
210D nylon – Internal zipped compartment.
The internal zipped compartment is made from 210-denier nylon: lightweight yet strong, with a smooth finish for easier packing and cleaning.
Polypropylene – Baked-in lining.
The interior liner is fused directly into the polypropylene shell, creating a seamless, weight-saving finish. This bonded design eliminates loose fabric and unnecessary parts while reinforcing the suitcase’s structural integrity.
The Mous Optimal Hardshell Carry-On is covered by our 25-year Limited Lifetime Warranty.
Key components — including the wheels, handle, lock and badge — are designed to be replaced at home with standard tools. Spare screws are included. For anything that can't be repaired at home, we'll arrange repair or replacement under the terms of the warranty.

What is UltraMatrix ® and why does it matter?
UltraMatrix ® is a high-performance woven composite made from self-reinforced polypropylene. It’s up to six times more impact-resistant and twice as stiff for its weight as polycarbonate, delivering exceptional strength without excess weight.
How light is the suitcase?
Our carry-on weighs just 2.8kg (2.9kg with the compression pad), compared to around 3.5kg for most polycarbonate cases, meaning more of your allowance goes on what you pack, not the case itself.
Will this fit in the overhead bin?
The Optimal Carry-On is engineered to the 55 × 40 × 20cm cabin format, which is compliant with most major airlines. We always recommend checking your specific airline's restrictions before you fly, as policies can vary.
How much can I actually pack?
The main compartment holds 36 litres — enough for a weekend away or a short business trip. There's also a 1.2-litre external quick-access pocket for travel essentials. At 2.8kg, the case itself uses significantly less of your cabin allowance than most mainstream alternatives, leaving more room for what you're actually packing.
Is it compatible with Mous packing accessories?
Yes. The Optimal Carry-On works with the full range of Mous Optimal packing accessories, including the Document Pouch, Toiletry Pouch and Tech Pouch. The internal divider pocket is sized to hold one accessory securely, with space for the others in the main compartment.
Is it repairable?
Yes. Key parts like the wheels, handles, lock and badge can be replaced at home using a screwdriver. If needed, our Customer Experience team can arrange professional repair.
What does the warranty cover?
Your suitcase is backed by a 25-year limited lifetime warranty, covering repair or replacement for manufacturing defects or faults under normal use.

Customer Reviews (3.8 / 5 · 5 reviews)
Ryan K. Dropped it down a flight of stairs at the airport by accident and it didn't even dent—the woven composite really is tougher than my old polycarbonate case. At 2.8kg I can finally lift it into the overhead bin without breaking a sweat, which makes the whole trip feel easier.
Ryan The woven composite shell feels noticeably stiffer than my old polycarbonate case when I knock on it, and it still slid into the overhead bin on a cramped regional jet with room to spare. I do wish the interior pockets were a bit deeper, but for the weight, it's a solid upgrade.
Zoe T. The 2.8kg weight is a game-changer for overhead bins—I can hoist it one-handed now. It survived a cramped train ride and a few curb drops without a scuff, though the zipper pull feels a bit flimsy for the price. Still, it's the lightest hardshell I've owned.
