I recently watched the first Harry Potter film (following news of Maggie Smith’s demise), and vividly remembered the scene where Harry bought his wand at Ollivanders. Rather than choosing the right wand, Harry was given a wand that ‘chose’ him. It fit his personality, was tailor-made to his greatness, and that moment when the wand and Harry shared a brief exchange of energy – it’s exactly the feeling you get when you discover the right bag. Zero hyperbole, but I’ve got 4 laptop bags in my house right now, ranging across a variety of styles and price points (one of them’s literally from AliExpress)… and neither of them fits my needs perfectly – my current daily driver is a bag that I’d say is 80% perfect.
Finding a bag that ticks all the right boxes is sort of like searching for that ideal wand. It needs to suit your style, be durable, and have enough versatility to keep up with the chaos of life. It’s a relentless pursuit until you stop and discover just the right bag that matches your needs. The folks behind the Mercurius Modular Bag were out to build exactly that bag – a piece of EDC that’s equal parts corporate-classy yet outdoor-durable, with enough modular elements to fit every aspect of your life in. Designed to be carried in 3 different ways, the Mercurius Modular Bag adapts to your style, whether you want a sling, a backpack, or a briefcase, making it your perfect go-to for work, a trip to the cafe for a quick meeting, an outdoor photoshoot, or even a quick getaway for a couple of days to relax.

A Shape-Shifting Bag for Every Moment
What makes the Mercurius Modular Bag stand out at first glance is its ability to switch forms depending on how you want to carry it. This is no one-trick pony—it can be worn as a backpack, slung over the shoulder, or carried like a briefcase. That’s three distinct styles in one, letting you transition from morning commutes to weekend adventures without swapping bags.
When you want to carry it as a backpack, the adjustable shoulder straps come into play. These straps are discreetly tucked away when you’re not using them, keeping the bag’s form neat and streamlined. Once you extend them, the bag sits comfortably on your back, distributing weight evenly to avoid strain. It’s ideal for longer commutes, biking through the city, or when you simply want to be hands-free.
In sling mode, the Mercurius Modular Bag turns into an over-the-shoulder carrier with a single, wide strap that can be adjusted to your height. This mode is perfect for quick access and short walks when you need something more casual than a backpack but not as formal as a briefcase. You can switch to sling mode easily by retracting one of the backpack straps and adjusting the other to act as the crossbody support.
For the briefcase style, simply retract all the straps and use the sturdy, built-in handles located at the top of the bag. This mode is where the bag really takes on a polished, professional look, perfect for meetings or more formal settings. Even though it’s technically the same bag, this transformation gives off a completely different vibe—like you’re carrying a high-end briefcase designed for business, not an everyday commuter’s backpack. The smooth transition between these modes makes it feel like you’re carrying three different bags in one, without the hassle of switching between them.
The Modular Magic Inside
The modular outer design extends to the insides too, with an insightfully compartmentalized layout. The designers have turned the interior into an organized dream, tailored for modern professionals and tech enthusiasts. You’ll find dedicated compartments for just about everything, from chargers to mice, phones, umbrellas, bottles, and even your AirPods. As far as laptops go (you know, the actual goods), this bag fits almost any model you can think of, from ultra-slim MacBook Airs to the large-and-in-charge LG Gram 17-inch. All iPad models slot in just as neatly (as do other tablets), so no matter your tech of choice, this bag has a place for it.
The Mercurius Modular Bag comes in classic black as well.
You can either slide your laptop right into the Mercurius Modular Bag’s dedicated laptop slot, or use an accompanying detachable laptop sleeve made from the same material as the bag itself, but with a built-in RFID-blocking liner for added digital protection. However, the sleeve isn’t just for protecting your laptop or giving it an extra carrying case—it also transforms into a desk pad or mouse pad. It’s a nifty addition for digital nomads or anyone setting up an impromptu workspace at a café or airport lounge. It’s thoughtful features like these that give the Mercurius Modular Bag its edge. The focus is clearly on adaptability—how the bag functions in real life when you’re constantly on the move.
Need more space? No problem. The bag’s expandable design gives you up to 40% more storage capacity, practically doubling your storage capacity. This extra space doesn’t come at the cost of the bag’s sleek profile, though. Even fully expanded, it maintains its minimal design, refusing to bulk up into an eyesore like other expandable bags tend to. Inside, it’s designed to work with modular packs, pouches, and travel cubes—making organization feel less like an afterthought and more like a core feature.
Tailored Extras for the Modern User
It’s the little things that push the Mercurius Modular Bag into the realm of “I need this.” While the bag itself has a built-in organization system, what gives it further meaning are the various pouches and travel cubes that fit perfectly into the remaining empty space, allowing you to carry your gear like never before. Aside from the detachable laptop sleeve, the Mercurius Modular Bag comes with an EDC pouch that has a magnet-based system that lets it snap onto the bag sort of like how a MagSafe accessory snaps onto your iPhone, aligning and positioning itself perfectly. The EDC Bag is ideal for any everyday carry, although Mercurius Modular Bag also comes with a Tech Pouch for tech accessories and a Bath Pouch for toiletries. All three modules fit perfectly into the backpack’s empty space, allowing you to compartmentalize your belongings in a meaningful way (after all you wouldn’t want your toothpaste and shampoo near your tech gear, right?) Furthermore, the Mercurius Modular Bag also provides a square-shaped Packing Cube for clothes that can be used with the bag, along with the Bath Pouch. In a way, you get to build your bags based on whether you’re heading out for a meeting, for something specific like an outdoor photoshoot, or a 2-day getaway.
Other clever details include things like a luggage pass-through feature, which is a godsend for frequent travelers. Simply slip it over your suitcase handle, and maneuvering through airports becomes a breeze. If you want to travel light, you can ditch the Mercurius entirely and just carry the laptop sleeve around with you, thanks to an add-on strap that turns it into a side-sling. The EDC Pouch can be independently carried like a man-purse too, thanks to that same clip-on shoulder strap.
Made from Cactus Leather, Built to Withstand Anything
The Mercurius Modular Bag doesn’t stop at smart functionality; it’s also eco-conscious. Instead of opting for typical leather or synthetic fabrics, Mercurius chose a cactus-based faux leather—an unexpected, yet refreshing choice. This material is as tough as it is sustainable. It’s water-resistant, durable, and designed to hold up to everyday wear and tear, whether you’re navigating city streets or dealing with a bit of rain. The combination of their unique design and cactus leather also gives the bag a luxe feel, so you won’t feel like you’re sacrificing style for sustainability. In fact, brands like Mercedes-Benz, BMW, and Porsche all use the same cactus-based leather alternative, embracing both durability along with material innovation. Meanwhile, the company does plan to offer a Smooth Calf Leather version of the bag to backers and users in the future. Alongside the durable outer material, heavy-duty zippers reinforce the design, ensuring the bag holds up under pressure, and a non-toxic suede inner further ensures your devices stay protected from elements as well as rough use. Furthermore, the cubes and modules are made from 100% recycled plastic fabric (the same fabric used by Prada in their high-end bags) echoing the sustainable approach.
The Mercurius Modular Bag is one of many I’ve seen over the years, but the one thing it does more than any of those bags is give me that ‘Harry Potter’s Wand’ feeling – it’s sustainable, durable, expandable, modular, stylish, and is designed to carry literally every object you’d want to carry. It comes in two rather evergreen colors – a tanned brown and a black; and can be carried in a variety of ways – as a sling, a backpack, a briefcase, or even strapped to your luggage. If that isn’t your definition of a perfectly designed bag, I don’t know what is…
