Design and Build
The Nomatic 20L Backpack is constructed from a synthetic, water-resistant tarpaulin material, a blend of 75% polyester and 25% nylon.

The overall aesthetic is sleek and professional, with a solid black colorway and a soft-shell design that maintains a structured yet adaptable form.
Physically, the bag measures 5.75 inches deep by 13 inches wide by 19 inches high in its standard 20-liter configuration. A key design innovation is its expandability; the capacity can grow by 20% to 24 liters when additional space is needed, all while maintaining a relatively compact profile.

Performance and Features
The performance of the Nomatic 20L is defined by its organizational capacity and protective features, tailored for tech-savvy professionals and travelers.
Organization and Storage
The bag’s standout feature is its extensive organization system, boasting over 20 individual pockets. This is designed to maximize space and keep tech, documents, and daily essentials neatly separated and instantly accessible. The main compartment and utility pockets provide structured storage, aiming to eliminate the need to dig for items during a busy day.
Tech Protection and Security
A dedicated, padded compartment safely houses laptops up to 16 inches in size. Adjacent to this, the bag includes a tablet pocket and, crucially, RFID-safe storage. This feature is designed to protect credit cards and passports from digital theft, adding a layer of security for travelers and commuters alike. The bag’s role in securing sensitive data aligns with a broader focus on protection; for foundational knowledge on the topic, consider our guide on the best cybersecurity books for beginners.
Travel and Carry Convenience
For travel, the bag includes a luggage pass-through sleeve, allowing it to be securely stacked on a rolling suitcase handle. Its dimensions are designed to fit under the seat of most major airlines, though the manufacturer advises checking specific airline requirements, especially for international flights. Two external magnetic bottle pockets provide easy access for hydration, though they are limited to bottles with a maximum diameter of 3.5 inches. The water-resistant material and zippers are intended to protect contents from light rain and spills.
Setup, Support and Ownership
As a ready-to-use backpack, no complex setup is required. The bag arrives as a fully functional unit, with the briefcase conversion straps integrated into the design for immediate use. The product is listed as an import and carries a manufacturer’s warranty, though specific warranty duration is not listed in the provided data. Owner reviews indicate that customer service has been responsive in some cases, honoring warranties for malfunctioning products like broken zippers after a claim process. The care instructions specify hand washing only, which is a consideration for long-term maintenance. The bag is a single, standalone unit with no listed optional accessories or upgrades from the manufacturer.
What Owners Say
Owner feedback for the Nomatic 20L is largely positive, with a high percentage of top ratings. Reviewers frequently praise the bag’s thoughtful organization, quality construction, and functional design. Many describe it as “well thought out” and appreciate the abundance of pockets and the secure, dedicated laptop compartment. The materials are often cited as feeling premium and durable, with the water-resistant properties performing adequately for daily protection.
Some common points of criticism from owners relate to specific design elements. A few users have noted that the zippers can feel stiff, particularly when navigating corners, though others report they loosen with use. There are isolated reports of components like tuck-away flaps or straps not being as robust as the main bag construction. It is worth noting that some reviews mention positive experiences with Nomatic’s customer service in resolving issues under warranty, contrasting with concerns from other users about support responsiveness. The rating distribution shows a strong majority of positive experiences.

Who Should Buy It (and Who Should Skip It)
The Nomatic 20L is an ideal choice for professionals, especially those in tech or business, who value meticulous organization above all else. It is perfectly suited for the daily commuter who carries a 16-inch laptop, multiple devices, documents, and needs quick access to all of them. Frequent travelers who want a personal-item-sized bag with airline-friendly dimensions, luggage pass-through, and security features like RFID blocking will also find it highly capable. If your priority is a single, durable bag that transitions seamlessly from a downtown office to a cross-country flight, this backpack is designed for you.
This bag may not be the best fit for everyone. Outdoor enthusiasts or students who need to carry large, wide-diameter water bottles or hydration bladders should look elsewhere due to the size-limited bottle pockets. Those who prefer bags made from natural fabrics like canvas or leather will not find that option here, as it is fully synthetic. Individuals who primarily need a simple, minimalist bag without extensive compartments might find the 20+ pockets over-engineered for their needs.

Final Verdict
The Nomatic 20L Backpack successfully executes its core mission: to be an exceptionally organized, secure, and adaptable carryall for the modern professional. Its greatest strength lies in its thoughtful design, which provides a dedicated, easily accessible spot for virtually every item a tech-dependent worker might need. The inclusion of legitimate security features like RFID protection and a robust, water-resistant build elevates it beyond a simple organizer to a genuine travel-ready piece of gear. The ability to expand for extra capacity and convert to a briefcase adds functional versatility that few competitors match.
Potential buyers should enter with clear expectations. The bag’s complexity and premium materials command attention to detail, which means some components, like the zippers, may require a break-in period. The limitations on bottle size and the need to verify airline fit are minor but real considerations. Ultimately, for the professional who views their daily carry as a mission-critical kit, the Nomatic 20L offers a compelling, durable, and highly functional solution that justifies its position in the luxury backpack category.
FAQs
Is the Nomatic 20L backpack truly waterproof?
The backpack is constructed from water-resistant tarpaulin material with water-resistant zippers. This means it is designed to repel light rain, splashes, and spills effectively. However, it is not advertised as fully waterproof or submersible, so it may not protect contents during prolonged exposure to heavy downpours or if fully submerged.
Can the bag fit under an airplane seat?
According to the manufacturer, the backpack’s dimensions allow it to fit under the seats of most major airlines. However, they specifically advise travelers to double-check their airline’s personal item size requirements, as these can vary. This caution is emphasized for international flights, where size regulations may differ from domestic standards.
What is the warranty on the Nomatic 20L Backpack?
The specific length and terms of the manufacturer’s warranty are not detailed in the provided product specifications. Owner reviews indicate that Nomatic does honor a warranty for manufacturing defects, with some users reporting successful claims for issues like broken zippers after contacting customer service and returning the faulty item.
How do you convert the backpack into a briefcase?
The bag features a patented strap system designed for this conversion. While the exact mechanism is not described step-by-step in the data, the system is integrated into the bag’s design. Typically, this involves tucking away the shoulder straps and using a handle or a secondary strap arrangement to carry the bag in a briefcase-style orientation.
