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 protective is this backpack?
Our Day Backpack offers an everyday level of tech protection, with a raised base that keeps your tech suspended 30mm above the bottom and separate sleeves with scratch-resistant materials. However, there is no AiroFoam® in this backpack, so it’s not suitable to protect against extreme drop and shock damage.
Is this backpack waterproof?
Our Day Backpack is built to handle light rain and showers, thanks to its water-resistant materials like 420D recycled nylon and coated 600D polyester. Plus, the concealed YKK® zip adds extra protection to keep your belongings safe and dry. Just remember, while it's great for everyday use, it's not a waterproof backpack, so don't go diving with it!
What’s the difference between this backpack and the Extreme Commuter?
Different people have different preferences, so we reimagined our design process for this backpack. The Extreme Commuter range prioritises top-notch tech protection and functionality, with AiroFoam® impact-absorbing technology and a more structured build. In comparison, our Day Backpack embraces a minimalist, effortless aesthetic in a lighter design. Both backpacks offer seamless access to the main compartments – just in different ways.

I absolutely love this backpack. It’s really beautiful, comfortable to carry, very sturdy and you can fit loads of things in it, all neatly organised. The front opening makes it very easy to get to the contents. Besides , I’ll be bying the matching laptop sleeve soon.

love the ultimate access with the central zipper
love the expandability ...for a compact satchel I can cram a lot inside, and then a little
only concern is that the top flap has already started to ripple, and by using the handle, it has started to change the structure a little.... wonder if a firmer support across the top of the bag would keep the integrity and a Sharpe line across the top of the bag

Excellent quality product as to be expected from Mous. I have given my old backpack to charity as this one is far superior as its replacement. The only two things I would change to this one are the addition of rubber feet or panel on the base to protect the material when putting it down on the ground to open it to load and unload items from it and change the shape of the locking hook to a smoother shape to allow it to be opened when it is fully packed, especially in bad weather and when in a hurry. Thoroughly recommended product.

It‘s a nearly perfect solution for my daily activities. Provides enough storage space done in a marvelous quality. I’m very happy with this purchase!

I have been using the Flap Backpack with Ultratex for a month now. I was looking for a light, durable, and not overly large backpack for everyday use. Overall, I am very satisfied, it is extremely lightweight and compact. I can truly say I found the exact bag I was looking for. Its price is a bit higher compared to standard bags on the market, but I believe it will definitely be worth the money in the long run. If you are looking for a bag like this, I highly recommend buying it.

Awesome backpack. This is the second item I've purchased from this company and the quality from these guy's is next level.

Best backpack I have owned. Great quality, excellent convenience. I really like the zipper on the front and the backpack looks small when putting little stuff in and gets bigger once more stuff is put in (smart use of magnets). 10/10!

Great backpack. Fits everything quite cleverly!
