Main materials
Main body and sides made from UltraTex®: an ultra-durable performance fabric engineered for serious strength without the bulk.
• It starts with a base of high-tenacity nylon – a yarn with tightly packed polymer chains for impressive abrasion resistance.
• Woven into this is a grid of UHMWPE fibres – ultra-high-molecular-weight polyethylene that’s 15× stronger than steel by weight – forming a ripstop to stop tears from spreading.
•The fabric is finished with a dual-layer PU coating to add water resistance and enhance overall tear strength..
The result? A material that’s lightweight, weather-ready and up to three times more tear-resistant than standard nylon.
Dual-layer PU coating: Creates a barrier against rain, dirt and grime to keep backpack safe and dry.
70D ripstop nylon: A lightweight yet durable internal lining designed to resist tears and abrasions inside the backpack.
Scratch-resistant sleeves: Soft lining helps prevent wear and tear on tech.
PU-coated YKK zippers: Smooth-gliding, durable and shielded from light rain.
G-hook closure: Aluminium hardware with magnetic side panels for secure, seamless fastening.

What is UltraTex® and how is it different from other materials?
UltraTex® combines high-strength nylon with ultra-high-molecular-weight polyethylene (UHMWPE) fibres to create a reinforced ripstop that’s up to three times more tear-resistant than standard nylon — yet remarkably lightweight. Finished with a dual-layer polyurethane coating, it offers excellent water resistance and long-lasting durability.
While some of our backpacks use heavier materials for maximum rugged protection, UltraTex® delivers exceptional strength in a lighter package. It’s engineered for those who want a durable, reliable backpack that stays light and agile, perfect for everyday use and travel.
How does this backpack differ from the Mous x Mercedes-AMG F1 Team Backpack?
This backpack offers the same high-performance design, durable materials and optimised organisation as the Mercedes-AMG PETRONAS F1 Team variant it just does not feature Mercedes-AMG PETRONAS F1 Team branding like the ultra teal trims and logo.
How well does this backpack protect my tech?
The Optimal Backpack is built for serious protection. Its AiroFoam® impact-absorbing technology shields laptops and tablets from drops og up to 1.2 meters. 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.
What’s the difference between this backpack and your Extreme Commuter range?
The Optimal Backpack retains the best elements of our Extreme Commuter range while reducing weight and maximising storage. Both offer tech protection, durability and weather resistance, but they differ in design, materials and organisational capacity.
Is the Mous sternum strap compatible with this backpack?
Technically yes, but it’s not the ideal fit. The placement of the nylon webbing on the straps limits how much you can adjust the sternum strap, so we don’t recommend it as the best solution for this backpack.

The quality is amazing, it lasted a little long to arrive but it was worth the wait, all the pockets feel solid, the zippers are special and strong everything you touch feels amazing, it is also very durable, I'm sure it will be with me A LONG time. The design is exquisite, very beautiful design and I really see and feel that my stuff is protected I can be calm if it rains or if by some reason fall to the floor while admiring how good it looks. Thanks Mous I'm glad you exist

As titled, optimal, feels mega. Love the Mercedes branding, would be nice if the Mercedes wasn't heat. pressed but something more permanent, will see how it holds out. Looking forward to traveling with it.

Overly advertised, the design looks sleak but too heavy for empty backpack. I bought it from the Netherlands, they shipped it from the Netherlands. The websites said free return within 30 days but there was no return labels. They made so many frictions to not be able to return. I had to contact them and had to wait days to get reply. But they told me to return to Poland instead and there is no return center in the Netherlands. So I had to keep the backpack because I don't want to waste 25 euros on return shipping cost.Shady business practice.

I bought this pack for a trip to Spain. It’s simply the best bag I’ve purchased. Plenty of pockets for storage and super light weight for travel.
A
A great travel backpack that is perfect for both business trips and everyday use. It’s practical, comfortable, and offers plenty of space for everything you need. I really appreciate its versatility and high-quality construction. Highly recommended!

This is an amazing back. It has all the space and compartments I need and could want. Although it is very comfortable I use it for cycling and I think it could have had a chest strap for this.
R
I like how the bag is optimised for the given size. It’s neat, lightweight and good quality. The bag has a good structure so holds its shape, the separate compartments for laptop are very clever design. Loving it!

All good, a lot of compartment and i like it very much

Hi, I use it for a week travel abroad. The product quality overall is great but there are few issues I like to comment.
1.Overall is quite heavy bag, due to protective features I supose, but when you carry for long time with content you can tell .
2. I found no convenient enough the G-hook closure, when in a hurry might slow you down.
3. Thicker Ziper it would be easier to use
4. pass-through strap slot I could prefer to place the bag vertical over suitcase and not horizantal to mix the contend incide.
I enjoyed quality of mess, design, variety of pockets, straps comfort.
R
I'm very pleased. The quality is better than I expected. A truly well-made backpack. Very practical and well-thought-out. It's not a cheap product, but it's definitely worth the price. Great quality. Thank you and best regards.

Great quality and highly practical backpack. Highly recommended.

Been using the bag for over a month now. Overall happy.
What is dont like and i think could do with improvements.
When the back is attached to a carry on luggage. The strap is extreme tight. Which sometimes can hurt my hand.
Also, I wished that instead of the backpack is in side way position. It could stand up. Side way just makes opening the main compartment so much harder.
Becasue of these 2issues. I would just carry the bag once I am at the airport.

I think the new Mous Mercedes-AMG F1 team backpack with UltraTex material is great. The material is super strong and lightweight. Storage compartments are well designed and not too numerous. The laptop sections is felt lined, smooth and supports both my work Dell laptop and Macbook Air 13". Central compartment is easy to open and access. and the top small section is handy for keys and loose items. A great backpack and one that I really enjoy to use for work and commuting.
S
I really like the backpack, storage is great but it is missing a few features that would make it a better for my needs.
1. An integrated key loop would be great for one of the quick access pouches.
2.The water bottlestrap needs to have a buckle of some sort so it can go through the handle of the bottle to better secure it. Without this my bottle often falls out on plane rides.
3. An integrated or included sternum strap for when the bag is fully packed down with weight would increase comfort.
4. On the hidden back passport pocket, a fabric loop to tie off. The pocket is the perfect size and placement for concealed carry, this would make it safer to do that.

Aside from my TNF bag, this is my go-to bag now. I haven’t seen anything like it here in the UK that has a bag like mine. It’s the bag I use every day since I got it. I think because of the price its not cheap 😊, This was my birthday gift to myself. I already have many TNF bags, but this is the only one I can truly say is worth the price. I just hope it lasts long and doesn’t look worn out over time.

I use this Protective Lid Backpack with UltraTex® every single day and I’m really impressed.
The materials are excellent from the durable UltraTex fabric right down to the zippers and buckles. It sits comfortably against the back with no pressure or bulging, even when fully loaded. It’s surprisingly spacious and very well organised.
Overall, this is a high-quality, practical backpack perfect for daily use. Strongly recommend it to anyone who values comfort, durability and thoughtful design.
Thank you, Mous!

This backpack is so good, light but sturdy, practical compartment, convenient for daily use for both office and casual
I
Specifically bought this to protect my tech & it did. Especially waterproof feature. The bag itself is kinda heavy.
P
It's a great bag, really. I only wish the bottle openings at both ends were just a little bit wider, actually more separated from the bag. If the bag is full, the side pocket does not stretch enough for a 1-liter bottle.
Also, you need to get used to the hook locking. When it is not locked, the hook just dangles there and sometimes interferes with the way.
Other than that, It's really high quality and perfect bag. I am very satisfied.
All the zippers are high quality, many storage compartments and pockets. Really recommend!

Amazing bag. Fits everything easily. Very comfortable. Best backpack I’ve owned.
