Boundary’s Prima System Could Make Other Backpacks Extinct

It’s nearly impossible to create a backpack that truly stands out from the rest. The issue? There are so many visually and architecturally stunning packs being designed.

And yet, we were caught starry eyed at the sign of the Prima System.

Created by the small company Boundary Supply based in Salt Lake City, this “ultimate modular travel pack” could become the last pack you ever buy.

And that’s Boundary CEO Cavin Nicholas’ dream. Not for the pomp that his pack is the best, but to curb the ravishing appetite for consumerism via truly resilient and multifunctional goods.

Lo and behold, his plan worked better than he could have imaged, earning 1,174% of its projected funding on crowdfunding site Indiegogo this June 2017 ($779,759).

From the outside, the Prima System looks like a hybrid messenger, hiking, backpack, camera bag, with pocket, clip and zipper design we’ve never seen before, let alone fathom.

Built around the Prima Pack, the full system includes a Verge Case (looks like a camera or lunch bag) and Fieldspace (made for iPads, chargers, pens, etc.).

Available in Obsidian Black and Mojave Tan, the Prima Pack expands from 25 liters to 30, with the attachable Verge case adding 10 liters of storage. The expandable and retractable nature of the Prima System serves its multi-use goal of being the perfect pack for weekend travel, daily work commute, or a quick 5-mile hike.

The Verge snaps into the side of the Pack (stellar for a couple cold ones or camera lenses), while the Fieldspace slides into a weather-resistant compartment.

Say ‘Adios!’ to the hassle of carrying four different bags.

The bells and whistles taking the Prima System to the next level include magnetic trims and buckles, YKK Stormguard zippers, an eyewear-specific pocket, secure RFID travel pocket, U-shaped opening for quick access, hidden G-hook compression straps to secure a tri-pod, and high-performance fabrics that are water and oil resistant.

Speaking of fabrics…

Four different Bluesign-approved fabrics are used in the Prima System. In fact, Boundary is stoked to be the first Bluesign-certified modular travel pack to-date. That means these fabrics were produced with regulated sustainable manufacturing methods.

The four threads include: 750 Denier Duramax Kodra (which sheds water and oil), High-Tenacity Hypalon (extremely durable protection from the elements.. hello, abrasion resistant!), Nywool Liner (odor and water resistant and protects a laptop or tablet), and Nylon Melange Liner (stain and odor resistant).

“We understand that every step in the manufacturing process and facet of business has an environmental and human impact,” says the team at Boundary. “So we pride ourselves as a brand that implements the Bluesign fabrics in every product we create. It ensures fair labor practices, safe working conditions, and sustainable fabric production throughout our supply chain.”

But is it comfortable? And can we get it dirty?

Double yes.

Prima is backed by a harness that regulates back temperature, wicks sweat, and distributes weight, since the pack is intended for biking, commuting, hiking, and you name it. Near the lower back is LOFT lumbar support padding, there’s a removable belt, and that same ventilated LOFT foam at the shoulder blades.

And whether you accidentally get a beer spilled on the back or sweat bullets on a summer trek, those trusty Bluesign fabrics keep the pack surprisingly clean and looking brand spanking new.

Chopard honors Sir Stirling Moss with Mille Miglia limited edition
Racing heritage: Chopard's stirling moss tribute and gts upgrade showcase lucent steel excellence
Chopard Mille Miglia press shot

Chopard honors racing driver Sir Stirling Moss with a Mille Miglia Classic Chronograph. At the same time, the brand updates its popular GTS Power Control with a new in-house movement. Both watches, released in 2025, use Chopard's Lucent Steel alloy, which is known for having the whitest, brightest steel finish in fine watchmaking.
The Stirling Moss tribute watch recognizes the Mercedes-Benz driver whose 722 300 SLR made racing history. The 40.5mm chronograph features a brass dial with a silver opaline finish, recalling the matte silver of Moss's "Silver Arrows" era Mercedes-Benz. Only 70 pieces exist, each individually numbered and priced at $10,800. The watch comes with a period-appropriate racing strap, featuring large punched holes and matching stitching.
Despite the high price, Chopard equips the chronograph with an ETA 2892 base movement rather than one of its own calibers. The movement is 3.75mm thick, runs at 4Hz, and offers a 54-hour power reserve. It is also COSC certified. Some collectors might expect an in-house movement at this price, but the 2892 is known for its reliable engineering, and many enthusiasts prefer it over alternatives like the 7750.
The Mille Miglia GTS Power Control 2025 Race Edition is even more appealing, as it finally receives Chopard's in-house 01.02-M movement. This caliber, measuring 28.8mm wide and 4.95mm thick, features cutouts reminiscent of cooling vents and uses color schemes inspired by car engines. It provides a 60-hour power reserve via a rotor with multiple openings.
A technical review notes, "This movement provides a big upgrade for the MM GTS, and it offers much movement for the price." The 43mm case houses a galvanized salmon dial with a circular satin finish. Grade X1 Super-LumiNova, with a black tint, creates a distinctive look against the salmon background during the day.
The GTS is priced at $7,630, with only 250 pieces available. It offers strong value, considering the in-house movement and Lucent Steel construction. The power reserve display, located between 8 and 10 o'clock, is styled like a car fuel gauge, reinforcing its appeal to car enthusiasts through practical design elements.
Both watches demonstrate Chopard's dedication to automotive history. They show how different approaches—tribute chronographs and technical upgrades—can appeal to various collector tastes. The Lucent Steel construction ensures both models display Chopard's renowned bright finish, which must be seen in person to fully appreciate.
The contrast in pricing and features makes the GTS Power Control especially attractive for enthusiasts seeking the quality of an in-house movement at a more accessible price.
