The ITR Studio One Backpack changes the game for everyday carry. As their first creation, ITR Studio have a genuine winner here, satisfying even the most demanding lifestyles, with all the right reasons to stand among the big EDC names.

And while there are certainly areas where I thought it could be improved- particularly the fidlock system, quick-access experience, and all-round stiffness – the modular and interchangeable nature of the One Backpack truly changes the way you can be productive, active, and organised in an aesthetically on-point manner; moving from city to city, country to country.

Breaking Down the One Backpack

While it may seem overwhelming at first glance with the many combinations available, the modular collection is quite straightforward. You have the One Backpack which is an outer shell that can function on its own. Pair it with any of five carry modules however – sling, gymbag, camera, suit and pouch – and you have a multi-functional carry geared to organise a variety of essentials you want to bring, transforming it into an entirely different beast altogether.

You can mix and match the modules you want, securely locked against the eight magnetic points on the One Backpack.

But versatility doesn’t stop there. The optional but worthwhile accessories are what brings the One Backpack together: the ITR interchangeable strap, Fidlock external strap and water bottle system. All together, it defines what the One Backpack is about – the backpack you’ll only need that purposely breaks away from itself for lighter or compact carries, uncompromising on what you want to bring and not, what you can bring.

Does the ITR Studio One Backpack stay true to it’s word on the Hong Kong based company’s debutant? Here’s my deep thoughts on using the range over the course of a month.

More than Meets the Eye

The One Backpack is a hybrid of sorts. On the One hand, the outer shell and full perimeter zip let’s you open up the backpack like a luggage. It gives you full exposure of the inner modules or main compartment area, able to freely manage the inside wholly.

On the other hand, it functions like a traditional backpack – front quick-access compartments on either side, a laptop and small access pocket on the rear to reach essentials without needing to take it off. This may take some time to get used to, but after a day or two, I found my rhythm and found it a great travel carry that kept my workflow efficient on the move.


There are plenty of internal pockets that surprised me with how much I could fit inside. A range of zipped and open pockets, I could store my hard-drive, mini tripod, camera extender pole, powerbank, cables, camera microphone, drone batteries, a book, Nintendo Switch and small accessories no problem. There’s more depth to the One backpack then I thought and that was exciting to know.

I found my rhythm and it suddenly became a great travel carry that kept my workflow efficient on the move.

The 30L capacity is capable, though as mentioned before, you’ll need to adjust the way you pack, thanks to the modular options that provide their own compartments and dividers. I got caught out in the rain on a few occasions, but the waterproof shell performed well, seeing heavy raindrops bead away effortlessly.

While the main compartment, laptop and rear compartments have waterproof, enclosed zippers, the front compartments don’t. I was told it was a design they were look to find a solution to for that all-round protection. I’d say 95% of the ITR Studio One Backpack is waterproof, so hope they can make it to 100% for that piece of mind and extra durability.

Maglock Modules for More

The magnetic lock system is the epitome of what makes the One backpack so different different from the rest. Eight attachment points can be find, with each supporting up to 35kg of weight. While I haven’t been able to put that to the test, they are definitely strong and robust.

Each module has magnetic points on the back that lock into place inside the One backpack. They click into place with a satisfying sound, while detaching by sliding to one side. More effort than effortless, but confidence inspiring and trustworthy with your equipment, exactly what you want.

The Camera module is what many may be interested in. As a content creator, my camera and drone are probably the equipment I always bring with me. The problem with normal backpacks are if you’re carrying a light setup, there are lots of empty wasted space. Buying a bag for every occasion is not reasonable (or efficient). That’s where the ITR Studio One Backpack comes alive.

It’s always handy to pack the interchangeable strap in my backpack because there are days when going minimal is all you really need. Made out of nylon that is waterproof with durable, waterproof zippers, it’s functional and simplistic inn design. Strap hooks on either side, as well as external attachment points keep you flowing, efficient and allow you to pack more than at first glance.

A neat feature to aid access through the One Backpack or on its own, is the rollable lid that secures in place with a button. This surprisingly works really well and found it useful in real-life though concerned about the lids structure over a period of time. If classic and subtlety is your thing, the modules are definitely worth a look.

The camera module offers a multitude of combinations to bring any kind of gear, but particularly camera and drone devices. I found carrying my Sony A7III, 90mm 2.8 G prime lens, RX100 III, Rode VideoMicro and Manfrotto Compact Action Tripod with ease.

Need to bring both? Well you can. Mostly. My Sony A7 III with an attached lens and Mavic Pro drone can be carried together, granted an angled and tight fit for the controller. Use an external Peak Design capture clip and you’ve got now space to with with for extra batteries and camera accessories. I went a whole day with it and found it lightweight and impressive overall.

Dope Sling Module

The Sling module had me excited. I actually had a lot of fun putting the Sling module to the test, carrying it around with me. Out of all of the modules, this is my favourite, simply because it’s the most versatile, portable carry that surprisingly stores a lot of different items.

You’ll find many pockets, starting with the external, full-width zipper pocket. You then have the main compartment for your larger items, an internal zipper pocket, and finally three inner, exposed pockets. The Sling has good depth to pack quite a few items. You could fit a mini tablet, notepad, pens, powerbank, cable, and small accessories inside which is impressive.

Whether it’s carrying to a lecture, a lightweight option while walking through the city, or a carry to house you’re compact camera and banking with the Nintendo Switch, there are many combinations you can fit, making this the most versatile module to use on its own.

You also have several options to carry it too – across your body, hanging off your shoulder, carrying it with the built-in hand strap or body tight off your shoulder. When I’m going ultra compact, I default to choosing the Sling module because I can still bring what I want. It’s that good. I think the Sling could benefit with a little more interior space, simply because if you’re packing the zipped front and inner pockets, it gets tight. Extra girth gives it a bit more breathing space. Otherwise, a favourite of mine hands down.

While I have the suit, sportsbag and pouch module, I didn’t have the chance to use them for this review, so will follow-up with reviews on each of the modules for those interested in these separately.

Optional extras that are essential

Carrying my tripod, a yoga mat, or sleeping bag is made simple with the Fidlock system. The two-attachment points click with ease, yet is sturdy and robust. I’ve enjoyed using this across my trod and the Fidlock water bottle, the latter something I can take off to drink while walking and reattach without thought.

The width of the backpack isn’t wide and the click of the attachment points mage me know it’s firmly in place. I find this works much much better then trying to do the same with my Peak Design Everyday backpack.

Something I would say is that thin items leave an excessive strap length hanging. Either a tidy or a shorter length would suffice as the length is generous to begin with.

Carrying my tripod or a water bottle no longer feels like a chore to carry. You just click and go.

That being said, the connectors are solid for securing my tripod. It’s been satisfyingly liberating to carry my tripod and not haze it feel like a chore anymore. The water bottle while simple in itself, adds versatility to the Fidlock attachment point in the One Backpack. 600ml capacity, a push and pull lip that’s lightweight and portable enough. The ease of attaching makes this a worthwhile optional accessory if you’re happy with the basic bottle, I suggest it.

A Big Step in the Right Direction

In many ways, the ITR Studio One Backpack works great as my everyday carry. An attractive design, plentiful of compartments, storage and pockets, and comfortable to wear all day long.

I’ve found a setup that carries my big and small items without feeling like I’m just shoving it all in, or organising the big stuff but needing something extra to manage the little items. The quick access and laptop compartments are the best yet that doesn’t feel like I’m scrounging around or struggling to take it out.

That modular system is what brings everything together and I feel confident in taking this backpack on weekend or a week getaway with all of my gear while living minimal. The modular carries themselves are good but nothing special on their own. Add it to the ITR Studio One Backpack and the interchangeable strap, and you’ve got a completely different beast.

Areas where I’d like to see it improve to be a true companion is a more durable outer shell where it isn’t vulnerable to dirt as I found whenever I travel; a robust frame or structure so the One backpack shell doesn’t collapse when it isn’t full, usually collapsing with the front pockets loaded as I unzip it.

For all the areas I felt the ITR Studio One Backpack could improve, it’s because this is one seriously impressive backpack that has been an absolute joy to explore, experiment, and naturally use. I havent been excited about an everyday carry for a while, and that’s primarily credit to the what the ITR One Backpack is not only now, but the foundations of what it means for the excited in future.
