The much-anticipated Boundary Supply Prima System just arrived on my doorstep. In case you’ve lived under a rock, the Prima System was launched off two wildly successful Kickstarter and Indiegogo campaigns raising over $1.8 million dollars. After doing some of my own research, I found myself clicking the “Back It” button on Indiegogo even though I had sworn never again to back another crowd funded project. Looking back on that decision, I wasn’t buying into the hype. First and foremost, the design of the pack system showed real promise and had some features that were truly unique. Boundary was also doing BlueSign Manufacturing. Which means they were adhering to stringent chemical standards, safe working conditions, and using energy from renewable resources to create a truly sustainable product.
The Prima System consists of the Prima pack, Verge Camera Case, Fieldspace Organizer. The Prima Pack is 21″H X 12″W X 7″D and can expand from 25-30L in capacity.

Out of the box, I immediately noticed how solid it was. I’ve carried a bunch of milspec packs in my years doing this and the Prima Pack felt like one. Part of that is due to the quality of the materials. Boundary went with 750D Duramax Kodra nylon for most of the outer shell (a Korean-made competitor to Cordura and every bit as durable). The bottom of the pack and other key wear points are reinforced with Hypalon. Nywool is used for padding and device protection. YKK Stormguard zippers with zipper garages protect most of the compartments from the elements. The overall build quality of the gear is some of the best I’ve seen from a new manufacturer. Especially considering the number of features that Boundary included in each piece and how they integrate together.
Of course, none of that matters if the harness is sub-par. I certainly need to carry the pack more before delivering a final verdict but first impressions are positive.

The padding is firm, which I generally prefer, and well structured. The raised back panel should provide good ventilation. I wish the strap pads were about an inch longer so less of the strap webbing was cutting into my sides, but they are not prohibitively short. The pack does not ride super high but I was able to set it up to my liking. The load lifters on the Prima are not particularly effective and probably could have been left off the production version. However, Boundary wisely included elastic keepers on all the pack straps so they stay out-of-the-way once adjusted.
The flap of the main compartment of the pack is secured via two magnetic buckles, which remind me of the Fidlock buckles that TAD has used on some of their latest gear.
To my eye, the shape of the Prima is similar to the Vertx Gamut, but unlike that pack, it has less structure and can expand to carry more in its main compartment. As an example, with the Verge Camera Case installed, I’m still able to carry all of my camera kit including my Mirrorless Sony A6000, couple of extra lenses, a Zomei Professional Tripod, and miscellaneous stuff like batteries, charger, straps, etc. in a Bond Travel Gear zippered pouch (reviewed here). Plus my TAD Raptor Hoodie with still room to spare.

The zipper flays open. Similar to Mystery Ranch’s patented Tri-Zip but not as fast and a little fussier to use with the flap setup. The buckles do help.
Of course, if you’re not carrying a camera, the Verge case can be undocked and removed providing even more capacity in the main. A zippered pouch and mesh stretch pocket give some much-needed small item organization.

Other notable features on the outside of the pack include a tripod pouch that, even expanded, won’t fit my Zomei tripod. It will fit my Slik Mini II and would probably take a GorillaPod also. There is a small strap to secure it (or other long items like an umbrella) near the top.

I love external water bottle pockets and the tripod pocket will also fit a full Nalgene-sized bottle like this 32-ounce Hydroflask.

There’s a top valuables pocket with a divider that includes a magnetic key chain. Unfortunately, the dock for the key chain compromises the entire pocket in that it could scratch the lenses on a pair of sunglasses or a smart phone screen over time. The pocket is large enough to hold my Oakley Sunglasses Case with a pair of Fuel Cells inside, so its less of an issue for me. But, I would have preferred that Boundary prioritized the utility of the pocket over the novelty of a detachable keychain, which I likely won’t use.

Probably the coolest feature of the system is the Verge Case. Based on early reviewer feedback of pre-production models, Boundary changed the snap configuration so that opening the outer zippered pocket of the pack also opens the flap of the Verge Case.

Behind the Verge Case flap is a hidden zippered RFID pocket, which can be accessed even when the Verge is docked.

The Verge case is lined with Nywool and includes one padded removable divider (I purchased an extra one). There are two internal mesh slip pockets on the flap for accessories and a top external zippered pocket.

The bottom of the Verge Case unzips to expand from a 5L to 10L capacity so it will fit longer telephoto lenses. I don’t find a waist strap particularly useful on a pack the size of the Prima, but it does detach and doubles as the Verge’s shoulder strap. It attaches to the case via two buckles, which are stowed hidden away in their own slip pockets when not in use.

The bottom features two compression straps to lash a light outer layer or a lightweight tripod. Overall, I’m quite impressed with the Verge. Boundary is also selling an insulated insert for the Verge that can be used as a lunch box or drink cooler. I purchased it but unfortunately its being shipped separately and will arrive at a later date.
The other accessory that comes with the Prima System is the drop-in Fieldspace Organizer. It docks magnetically into the laptop compartment.

The case includes Hypalon pen loops and elastic straps for other small items along with two zippered mesh pockets.

The organizer has a magnetic flap with a Nywool lined pocket, which will fit up to a 13″ laptop or an iPad Pro. There’s also a slip pocket behind it.

Unlike the magnetic keychain, the backside of the dock for the Fieldspace is not exposed in the laptop compartment, which is separated by another NyWool divider. It’s slightly raised, well padded, and can fit up to a 17″ laptop. I prefer zippered top loaded drop-in laptop sleeves for ease-of-use and this one is well done.

The only major concern I have with the pack so far is the weight. It felt heavy out of the box so I pulled out my digital travel scale. Just to ensure it’s accuracy, I started by weighing a TAD Axiom X25. TAD listed specs state 3.2 lbs. My scale weighed it empty at 3.22.
![26167214_10211554566364424_8888429616524959589_n]()
Then, I weighed the Prima Pack.
![DSC00594]()
The Prima System’s unpacked weight, including the Verge and Fieldspace, is 5.53 lbs. Now, due to the stout suspension system, you don’t notice it as much as would on some other packs. I’ve carried lighter packs that have fared much worse comfort-wise. But, it’s definitely a concern and one that I’ll have to gauge under real world use as I continue to carry it.
CONCLUSION
I believe, despite some of the issues I’ve identified, that the Boundary Supply Prima System is the real deal. The value of this package is astonishing considering it can be purchased off their website for $199. Yes, since the company is based in Utah, I would have preferred it be to be made here. And they have stumbled out of the gate by over promising and under delivering on a November drop date and then again by Christmas (even after charging an additional $25 for “expedited delivery” to the US). But, it’s hard to argue with the result and you’d be hard pressed to find a more high quality, full featured EDC pack anywhere regardless of price.
I’ll share more thoughts on the system as I use it more. Stay tuned!
