Protective Lid Backpack

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.

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.

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!

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.

Great quality and highly practical backpack. Highly recommended.

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!

Specifically bought this to protect my tech & it did. Especially waterproof feature. The bag itself is kinda heavy.

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!

The backpack is beautiful and functional with many pockets in and out of the bag, I love the new material on the bag, I would definitely recommend this bag and the company itself wherever I go because their products are to me the highest quality that you can get nowadays which you don’t to often now. Thank you to the Team at Mous and please continue to make such beautiful products!

The Material Glow-Up

For me, the fabric choice is the biggest win. The material on my Extreme Commuter was tough, but it was a lint magnet. The Optimal's shell? Way classier, lighter, and it just doesn't attract dust or fuzz the way the Extreme Commuter's material did. It stays looking clean and professional without you having to constantly lint-roll it, which is a massive quality-of-life upgrade. It feels premium and still feels durable, but without the stiff, bulky feeling of the Extreme Commuter model.

Smart Design, Zero Snags

This is where they hit the "optimization at the right ends" sweet spot. Yes, maybe the Optimal offers slightly less raw protection than the tank that is the Extreme Commuter, but the trade-off is totally worth it: it’s lighter, significantly more comfortable, and looks much more elegant.

Plus, the minor annoyances are gone. The robust zippers now glide effortlessly. No more having to wrestle with a snagged zip just to get your laptop out! As for the G-Hook—it takes a minute to figure out, sure, but once you get the motion down, it's second nature and feels incredibly secure. It blends right into the clean, minimalist look of the bag.

Final Word: Why I’m Sticking With It

This backpack is pure proof that sometimes, less is more. Mous took their core commitment to quality and applied it to creating a truly refined, everyday experience. It perfectly balances a sharp look with practical features that just work. If you’re looking for a highly functional, sophisticated, and comfortable daily carry—especially if you know the quirks of their other packs (like the Extreme Commuter)—the Optimal 25L is the one to get.

Review updated:

Had a message from Mous, lovely email from their customer team. They took the feedback well, whether it makes any difference I'll never know, but great to here they listen and happy to engage.

I bought this bag for our overseas travel, and it did great. While I'm still annoyed at the hook, it did the job well, it never came undone by itself.

Rating changed to 3 stars.

The metal “hook” you use to hold down the flip is hateful. I thought you guys were about precision!

The hook doesn’t release predictably when you need it, gets caught on the fabric loop on the way out and because it fabric, it deforms and when you go to tie down the flap, the metal hook gets stuck on the way in.

When I buy a $400 backpack I want precision and predictably, I want to to be able to release and lock down with one hand in a single motion.

TBH I was surprised and disappointed when I realised what I received, I had read about this new clip you had on your other bags and just made the stupid assumption that’s what I was getting.

Get rid of the hook/loop solution!!

If I can make another suggestion, can you please put a loop inside the bag? I was looking for somewhere to hang my battery pack, plus other things that come with loops that would be easily accessible if a loop was near the top.

Plus, it seems you’re really good at fabric loops ;)

It would have been a 4 star review but as I have to live with the hook, it will be all I think about for the life of the bag.

I travel internationally with this backpack, and it works flawlessly! It’s comfortable, durable, ergonomic, and stylish. Best of all, no extra carry-on fees! I absolutely love this backpack. Highly recommend! ✈️🎒

Adoro il mio Protective Lid Backpack. La capienza è perfetta per l’uso quotidiano e l’apertura del vano principale, con le cerniere che lo aprono totalmente, aiuta a riempire e a prendere oggetti con facilità. Le cerniere di questo vano poi sono protette da una copertura con un gancio di metallo, difficile da sganciare se la fettuccia che lo tiene viene tesa. Nel vano dedicato al pc riesco ad inserire senza difficoltà il mio vecchio laptop da 15”, che non è un campione di sottigliezza. In più ha tantissimi vani esterni ed interni di medie e piccole dimensioni, dove trovano posto ordinatamente tanti oggetti di uso quotidiano. Non cambierei questo zaino con nessun altro.

Excellent build quality and stylish enough that my fashion sensitive teenage daughter will use it daily.

I LOVE IT

my new BFF!

It has many compartments and features, great

Ein bildschöner, gut zu tragender und vor allem extrem durchdachter und praktischer Rucksack. Es ist wirklich ein Vergnügen, ihn zu nutzen. Ich war zunächst leicht skeptisch angesichts der immer sehr überschwänglichen Anpreisung von Mous. Aber einige Wochen intensiver Nutzung haben mich vollständig überzeugt. Klare Kaufempfehlung!
