How protective is this backpack?
The Optimal Travel Backpack is built for serious protection. A separate tech compartment is equipped with AiroFoam® impact-absorbing technology, protecting laptops and tablets from drops and shocks. It's also highly water-resistant, keeping your gear safe from rain, spills and splashes – though we wouldn’t recommend submerging it in water. Whether you're caught in a storm or on the move, your tech stays protected.
Are the accessories included?
No, modular accessories like the Optimal Compression Wardrobe are sold separately. You can purchase them individually or as part of a bundle to customise your setup.
Can I use this backpack as a cabin bag?
Yes! At its standard 40-litre capacity, the Optimal Travel Backpack meets the cabin bag size requirements for most major airlines and fits in overhead bins. While we've thoroughly compared its dimensions with airline guidelines, we can’t guarantee compliance in every case due to airline-specific policies. It’s not designed to fit under the seat as a personal item.
How do I clean or treat stains on the Stone backpack?
To keep your Stone backpack looking its best, we recommend spot cleaning only. Use warm water, a mild detergent and a soft cloth or sponge to gently lift any marks or stains. Avoid harsh chemicals, bleach or machine washing as these can affect the material and water resistance.
After cleaning, let it air dry fully before use. For best results, try to treat stains as soon as possible to prevent them from setting.

Still not received my waist strap which was missing upon arrival. Used it once in France strapped to the back of a motorbike. Along with the other items it performed well. Heavy rain did not penetrate the shell. It’s early days and Australia is next so I shall see how well it fits in with a long haul flight.
Really disappointed with the customer service regarding the missing strap. I still have not received an answer or the strap.

As stated loved it!

I’m very disappointed with this product.
There’s a problem I’ve never experienced with other premium backpacks: the zippers on this Mous backpack keep sticking. They don’t run smoothly, which makes opening and closing the bag unnecessarily difficult.
I use several bags for my work as a media trainer: an office backpack from Tumi, a laptop bag from Samsonite, a camera trolley from Manfrotto, and a garment bag from Victorinox. All of them have smooth, reliable zippers — some of them even longer than those on the Mous backpack.
This is a basic feature I expect to work properly, especially in this price range.

Multiple grip pieces on the end of the zip cords have fallen off on the very first use. I assumed that reasonably high price point would be a high build quality completely wrong from my experience. I feel like I have been scammed by insidious algorithm advertising.
C
For now everything is working perfect with this backpack. But I am a little concerned about the solidity of the stitches near the main compartiment of the backpack. Plus the strap on the chest fell off a few times… this should be fix permanently to the shoulder strap. 👍🏻

Zaino molto elegante e spazioso

Great back pack. Just used on short weekend trips in this country at the moment. Can’t wait to see how it performs when away for long weekend abroad
A
It's a really good looking bag. Really ... but it's to heavy empty. Need more zippers for the internal pockets. Scary to drop things when opening the pocket bag. The bag cost me to much in CAD. Bag + Customs fees. Total 800$ CAD. Hope I will love it in the long term.

I would like to say first by saying this backpack might not be for everyone. I have been in market for relatively big backpack I can use for my day to day travelling at work with lots of gear needed for my job but also wanted to find all in one solution that if I need to travel somewhere for few days it can handle that as well. And oh boy I couldn't be more happier with quality and how comfortable this backpack is for me. I get it that some people might complian about the weight of this backpack but I will say one thing to them. Grow up, your gear it protected same as your clothing and other things you need to carry

Well designed and fabricated !

100% it kept what had been promised! It is so functional, practical and at the same time stylish. I am very happy with it and recommend it. For one week, laptop and other stuff for work, clothes, documents, no problem and well organised... just great.

Great pack overall. Two thing though: the zippers are a bit hard to open/close and I constantly feel that I'm going to rip one broken.. The bottle side pockets are a bit narrow, so my aluminum drinking bottle was hard to fit, and I can not really close the pocket with that bottle. Other than that I'm very satisfied.
Yeah, and another thing. The wardrobe compressor was a bit heavy and a bit bulky in itself, so I ended up not using that at all. Instead I went for cheap lightweight packing cubes.
P
Excellent product. Very practical and flexible. I think you are onto a winner with this product range. You shold market it more heavily, as I don't see many of them around right now.
A
Great backpack, but - the zippers are way to small and flimsy.
P
Quality looks good , delivery was slick - minor (tasteful) coloured highlights on zips would be useful as visibility for compartment access can be tricky especially in low light conditions
A
It's a really good vacation bag, that I with back issues, can travel with comfortable.
S
Great for short holidays, work and gym

I had seen the drop tests of the other mous backpacks, I was eager to buy one of them but opted for the travel backpack for the additional space.
Using the packing cube I am able to store around 15kg.
The loops for clips on the side are useful. Quality seems very good.
The cons:
-The zippers are difficult to close and don't feel strong enough
- front pockets arent usable if backpack is full
- chest clip is difficult to undo
J
Good quality but not user friendly. zips get stuck in eachother, if you want quick access to large things you need open yhe whole bag. The handle at the top.is too tight for easy grab and go. The inside mesh netting is too loose so things get stuck as you put them in.
A
Fantastic
quality

Awesome, but gutted the packing cube didn’t come with it. Would make it perfect!
A
It is well done!
A
Fan-freakin-tastic!
I used this for a four-day weekend and it was great. It had enough space with the compression pouch to fit everything I required.
J
What a fantastic product. I can fit at least a weeks worth of clothing and all my tech in this single backpack. The one slight issue is that the zips are a bit sticky and take a bit of persuasion to open and close. This is probable because they are new and will get better after I use it more and more.

I really fancy camo style or a sandy colour instead of the Gerald Ford black. The chest strap needs to be wider as it digs in.
