Boundary Supply Prima Exterior

The Prima Backpack boasts distinct features that set it apart. The prominent full-length single rail zipper and dual magnetic outer clips immediately catch the eye. The innovative lift-upward action of the clips, coupled with the fold-over closure of the zipper at the top, ensures exceptional security, safeguarding your belongings from potential pickpockets. This bag’s design is far from ordinary, making any attempt to tamper with it conspicuous. The top lid houses a clever pocket, concealing a magnetically sealed inner pouch lined with Water Resistant Nywool™, providing an added layer of protection and comfort for your items. The YKK Stormguard® zippers throughout the bag are effortlessly smooth, and their weather sealing never hinders usage. When combined with the robust Barricade™ DWR coated Nylon, the bag attains an impressive level of water resistance. While the Prima Backpack is well-equipped to endure heavy downpours and waterfall adventures, it’s important to note that it isn’t meant to double as a flotation device or accompany you for a swim.

On one side, you’ll find a standard bottle pouch that conveniently doubles as a travel tripod holder, complete with a discreet hidden strap at the top. Additionally, a cleverly concealed pocket is integrated within the bottle pouch for added storage. The bag also features straps along the base for attaching a tripod. On the opposite side, you’ll find the entry point to the Verge Case when it’s mounted inside the Prima Backpack. This bag adheres to the modern preference for a large side access point on camera bags, allowing easy access without the hassle of a top flap.

To complement the rugged nature of this bag, it boasts a robust top handle emblazoned with the Boundary logo, a smaller grab handle on the side, and well-cushioned back straps securely attached beneath a smooth protective layer. The removable waist strap also serves as a shoulder strap for the Verge Case, offering versatility for external use or as a standalone day pack. The Prima Backpack features Boundary’s LFT™ EVA foam on the back, providing substantial padding for added comfort and breathability, ensuring a balanced load distribution. This padding also extends external protection for the laptop pouch, which is conveniently accessible from the top of the bag. This is also where you’ll find the Fieldspace storage. In essence, the Prima Backpack seamlessly marries style, functionality, and comfort, making it a standout choice for discerning photographers and adventurers alike.

Exterior Features:

  • RFID safehouse hidden pocket

  • premium shoulder bag pads for relaxed carry

  • water bottle pocket

  • side access pocket and other hidden pockets for storage

  • amazing travel backpack which is great for longer travel or shorter weekend trips

  • multiple access points through exterior pockets

  • padded top through grab handle

  • premium exterior fabric

  • sternum strap

Boundary Supply Prima Interior

The Prima Backpack prioritizes spaciousness over internal compartmentalization, focusing on accommodating a generous volume of items. Inside, there’s a discreet zipper pocket on one side, a deep mesh pocket on the other, a sizable soft pouch (ideal for a laptop or documents), and an RFID-secured pocket on the inner side access door.

This expansive interior allows for convenient loading of large items or stowing numerous smaller ones. For efficient packing, it’s recommended to complement it with Boundary Supply’s available packing tools. The ability to lay the bag flat and unzip it entirely simplifies the packing process compared to inserting items from the top. However, the true standout feature of the Prima Backpack’s interior lies in its compatibility with the Verge Case.

The interior sidewall of the backpack features two securely built-in button points, while two more are strategically positioned on the inside of the side entry door. This ingenious design allows unzipping the outer zipper to simultaneously open both the backpack and the case. It ensures a secure attachment of the Verge Case inside the Prima Backpack, effectively creating an internal padded camera cube.

If you prefer, you can leave the shoulder strap attached to the Verge Case, especially if it was previously utilized externally. Alternatively, you have the option to remove it, reducing any potential interior clutter and bulk. This thoughtful integration enhances the versatility and functionality of the Prima Backpack, making it an ideal choice for photographers and adventurers seeking a streamlined and organized packing solution.

Interior Features:

  • padded laptop compartment that is removable

  • tech sleeve for wired components

  • detachable travel organizer

  • fits interior mesh pouches

  • document sleeve

  • heavy duty material

  • fits overhead bins

  • immediate access points for convenience

Storage Capacity

The Boundary Supply Prima Backpack is impressively sleek for its capacity, allowing you to carry a substantial load even before expanding it. If you’re one to embark on day trips or longer journeys with heavier gear, this bag proves to be a perfect fit.

By utilizing the Verge Case on the exterior and fully extending both it and the Prima Backpack, you can comfortably accommodate up to 41 liters of gear, plus a tripod. When combined with another of Boundary Supply’s packing solutions, you can manage around 47 liters or more—an astonishing feat.

In our assessment, we opted for a more practical loadout, steering clear of showcasing the sheer volume of possessions that could potentially fit in. 

The Fieldspace seamlessly clips into the rear section of the bag, where you’ll also discover the dedicated laptop pouch. We could effortlessly slide in a 13″ Macbook Air, while the front pockets had ample room for a couple of USB hard drives and an assortment of charger cables.

There’s a magnetic-lidded pouch designed to snugly hold the compact 13″ laptop, along with another sleeve suitable for A4-sized documents, magazines, or booklets. The Verge Case is thoughtfully designed to house a Canon 5D MKiii with a 24-70mm lens attached, with extra space for spare batteries, memory cards, and additional accessories.

If you’re a mirrorless shooter, rest assured, a Sony A7iii with a Tamron 28-75mm attached can comfortably fit, and there’s even room for a Samyang 35mm f/1.4 alongside another lens. We recommend investing in dividers to keep your lenses securely in place, preventing any unwanted movement.

The Verge Case further features two mesh pockets stitched into the lid, along with an outer zip pocket perfectly sized for a phone or a slim USB battery pack. Even with all the aforementioned items loaded, the Prima Backpack still offers a generous amount of interior space. We tucked a jacket at the bottom under the Verge Case and placed the rest of our cables and essentials on top, all without the need to expand the bag.

Additionally, the backpack boasts a top-access laptop pocket at the back, capable of accommodating laptops up to 17″ in size, even when the Fieldspace is fully loaded. We had no issues fitting the Fieldspace with the items mentioned above, alongside a 15″ gaming laptop.

When you unzip the rear section, it opens wide, allowing for easy insertion of a laptop or unhindered access to unclip the Fieldspace. A nifty magnetic keyclip can also be found tucked away in the top lid pocket. It detaches effortlessly when needed and securely fastens back in place when not in use.

However, it’s worth noting that the black paint on the keyring is susceptible to scratching when attaching keys. Nevertheless, it remains incredibly useful, especially for those prone to misplacing keys within their bags.

Value for Money

The price set by Boundary Supply for the basic kit of this bag strikes me as reasonable. It’s impressively durable and comes in a well-proportioned package. While there are design choices that don’t align perfectly with my preferences, considering the overall quality and value it offers as a whole, we are quite satisfied with it. It’s certainly well-suited for both the daily commute and the next adventure.

For those seeking more than the basic kit, Boundary Supply offers several predefined customizable packages. These bundles come with additional packing solutions at a discounted rate compared to purchasing them separately. They’ve been thoughtfully crafted to seamlessly integrate with the Prima System in various ways.

Additionally, Boundary Supply has introduced an X-Pac variant of the Prima System, known for its exceptional durability. This option comes at a higher cost, but it’s worth it for the added toughness, featuring Kevlar Fiber X-Ply. If the standard Prima System wasn’t already prepared for anything, this takes it to the next level.

For individuals engaging in serious, demanding activities, the X-Pac variant is the way to go—there’s little doubt that this bag could weather just about anything. It’s truly an exceptional blend of materials, elevating an already outstanding package. The Verge Case and Fieldspace integrate relatively well with the Prima Backpack, but as we’ve mentioned, it’s not without its flaws, which are worth noting.

While these drawbacks aren’t deal-breakers, they do deserve mention, considering there are far more positives to highlight about this system.

One downside we found with having the Verge Case on the inside of the Prima Backpack is that it’s only attached on one side of the bag, leading to noticeable sagging when loaded with camera gear, especially when expanded.

Additionally, there’s a significant vacant space between the bottom of the Verge Case and the Prima Backpack. While this aids in protecting your gear from direct contact with the base of the bag, it does present a challenge if you’ve placed numerous small items inside. They tend to gravitate towards the bottom, making it somewhat bothersome to retrieve them. Although this space at the bottom can still be utilized, it doesn’t integrate as seamlessly as the rest of the bag, which feels somewhat disappointing. We found a workaround by tucking a jacket down there, which also helped support the Verge Case, but it did feel like a minor design oversight.
