BearVault BV One Revolutionizes Backpacking Gear with Collapsible Design

Updated March 26, 2026 08:51AM

For years, the bear canister has remained a cumbersome but necessary evil for backcountry adventurers. Often characterized by their bulk, unwieldy nature, and the general desire to leave them behind, these essential pieces of safety equipment have seen little in the way of true innovation for over a decade. However, the past year has shattered this stagnation, witnessing an unprecedented wave of creativity with three distinct and forward-thinking reimaginations of the humble food storage container. Joining the ranks of the REI Traverse, with its clever dual-canister design, and the Grubcan Wave, which prioritizes a tent-like carry for enhanced packability, is the much-anticipated BearVault BV One. Launching today, this groundbreaking product boldly claims the title of the world’s first "collapsible" bear canister, promising to redefine the user experience and alleviate a long-standing pain point for hikers and backpackers.

After an extensive four-month evaluation period, the BearVault BV One has emerged as a standout performer, excelling across all critical metrics. It has proven itself to be one of the lightest canisters currently available on the market, offering remarkable ease of use, and a generous capacity suitable for the majority of hikers. Most impressively, it achieves a level of packability that is simply unmatched by any other canister tested to date. This innovative design is poised to significantly reduce the bulk and inconvenience associated with carrying essential bear-resistant food storage, a welcome development for anyone venturing into bear country.

The standout feature of the BV One, and arguably its most significant selling point, is its ingenious adjustability. Unlike traditional canisters that maintain a fixed volume, the BV One incorporates a threaded mechanism that allows users to seamlessly screw the top half down into the lower section. This innovative system effectively reduces the canister’s overall volume and, consequently, its packed size. The functionality of this threading system is exceptionally well-executed. Once the desired volume is achieved, the threads lock securely into place. Users then engage a series of locking tabs – a mechanism that will be explored in greater detail later – by continuing to turn the top section clockwise. This adjustability offers a substantial three inches of variable height, allowing the canister to transform from a maximum height of 8.5 inches down to a compact 5.5 inches. This dynamic sizing capability is a game-changer for optimizing pack space throughout a trip.

While the REI Traverse offers a degree of adjustability through its modular design, featuring a removable middle section that can be stowed externally, the BV One presents a more elegant and integrated solution. The Traverse’s system essentially offers two discrete sizes – large or small without the middle extension. In contrast, the BV One’s continuous threading allows for a nuanced compression, akin to that of a compression sack. As hikers consume their food supplies over the course of a trip, they can progressively tighten the threads, thereby shrinking the canister to precisely match the diminishing volume of their remaining provisions. This feature not only saves valuable pack space but also contributes to a more balanced load as the trip progresses, a subtle but significant benefit for long-distance hikers.

In terms of dimensions and weight, the BV One presents a compelling package. It is offered in a single size that boasts a maximum capacity of 8.3 liters (approximately 505 cubic inches) and tips the scales at a respectable 1 pound, 15 ounces. The true magic of its design, however, is revealed when fully collapsed, reducing its volume to a mere 4.6 liters (282 cubic inches). Crucially, due to its adjustable nature rather than a modular system, the weight of the BV One remains constant regardless of its collapsed state.

When compared to its competitors, the BV One’s capacity is on the smaller side. It is well-suited for approximately 4 to 5 days of food for a solo hiker, depending on the efficiency of food packing. This capacity might present a challenge for shared use on trips exceeding two days. For context, established canisters like the BearVault BV500 offer 11.5 liters, the REI Traverse provides 11.3 liters, and the Bearikade Expedition boasts an expansive 14.7 liters. Therefore, for individuals or groups requiring significantly more storage space, alternative options would likely be more appropriate.

However, where the BV One truly shines is in its weight-to-capacity ratio and overall competitiveness. At 1 pound, 15 ounces, it stands as a highly competitive option, lighter than all previous BearVault models with the exception of the smaller 3.5-liter BV425 (which weighs 1 pound, 12 ounces). The REI Traverse, in stark contrast, is considerably heavier at 3 pounds, 9 ounces. The Grubcan Wave matches the BV One in weight but offers a smaller 6.6-liter capacity. The only canisters that marginally outperform the BV One in terms of absolute weight efficiency for their size are Bearikade’s premium carbon fiber models. The Bearikade Scout, for instance, offers 8.1 liters of capacity and weighs in at 1 pound, 12 ounces – approximately the same volume and three ounces lighter than the BV One. This performance comes at a significant cost, with the Bearikade Scout retailing for a steep $326, and it notably lacks the BV One’s crucial collapsible feature. This comparison underscores the remarkable achievement of the BV One in integrating a collapsible design while simultaneously minimizing weight. The design team at BearVault has expressed a desire to introduce larger iterations of the BV One in the future, as the threading system appears robust enough to translate effectively to larger volumes.

The form and function of the BV One, while revolutionary, do introduce a slight learning curve compared to more conventional bear canisters. The adjustable threading, while incredibly practical, makes the initial setup and breakdown process a touch less intuitive. The canister is comprised of two equally sized sections, requiring hikers to pack each independently before screwing them together. Determining which section constitutes the "lid" can be a minor point of confusion. While it is generally easier to unlock the canister with the wider section positioned at the top, this configuration necessitates a subsequent flip to prevent food from spilling out. The bottom section cleverly incorporates a removable plastic divider designed to keep provisions secure during this transition.

The BV One also features a novel locking system that deviates from the established BearVault line. Instead of the small plastic tabs common to other models, the BV One utilizes two rubberized buttons located on opposite sides of the upper section. Pressing these buttons simultaneously disengages the locking tabs situated on the rim of the lower section. The sensation is akin to opening an oversized pill bottle. This dual-button release requires two hands but offers a significantly improved user experience compared to the often-fiddly mechanisms of other BearVault canisters, making it the fastest-opening canister tested. However, in terms of overall ease of use, considering both strength and dexterity required, the Grubcan Wave remains the benchmark.

It is imperative to note a crucial detail regarding the BV One’s locking mechanism: it is only fully engaged and secure when the canister is at its maximum height. This is the configuration that must be maintained overnight to ensure adequate protection against bear intrusion. During testing, it was also observed that rapid threading or unthreading could potentially cause the lock to "skip" a tooth. While this is considered a low-probability risk, it represents a potential point of failure against a determined bear. Nevertheless, once the lock was properly engaged, it remained secure throughout all testing scenarios.

Navigating the landscape of bear canister regulations and certifications can be a labyrinthine experience for consumers. The patchwork of approvals means that a canister deemed compliant in one national park or wilderness area might be strictly prohibited in another. The BV One, fortunately, holds approval in a significant number of popular hiking destinations, with a few notable exceptions. It is IGBC (Interagency Grizzly Bear Committee) approved, signifying compliance with the standards required in the vast majority of bear country, including iconic locations such as Yellowstone and Grand Teton National Parks. However, it is currently not approved for use in Yosemite, Kings Canyon, or Sequoia National Parks, and it is unlikely to be added to their approved lists in the foreseeable future. While not yet approved for Olympic National Park, there is a strong likelihood of its inclusion on the approved list within the current year. This regulatory landscape underscores the importance of verifying specific park requirements before embarking on a trip.

In conclusion, the BearVault BV One emerges as the premier bear canister on the market for the vast majority of hikers, provided their food storage needs do not exceed its capacity. Its compelling blend of affordability, remarkably low weight, and highly practical features is exceptionally difficult to surpass. Most significantly, its unparalleled adjustability offers a tangible improvement in user experience, making it considerably less cumbersome to carry as a trip progresses. At $120, it represents a slight premium over other BearVault models, the REI Traverse, and the Grubcan Wave. However, based on extensive testing, this $30-$40 premium is a worthwhile investment for most users, particularly those who value packability and convenience. The primary drawback to consider is its limited volume. Hikers who frequently share a canister with their partners or embark on solo expeditions requiring more than five days of provisions will find the BV One to be too small.

For the dedicated ultralighter, the BV One may not hold the absolute title of the lightest canister available – that distinction still belongs to the Bearikade line. However, the weight difference is a mere matter of approximately three ounces. The BV One’s true advantage for ultralighters lies in its collapsed state, which allows for exceptionally easy internal packing, even within the most compact ultralight backpacks. The often-awkward pairing of a bulky, rigid canister with a streamlined, minimalist pack is significantly mitigated by the BV One’s space-saving design. This degree of packability likely justifies the marginal weight penalty over a Bearikade for the majority of ultralight enthusiasts, offering a more harmonious integration with their carefully curated gear setups. The innovation demonstrated by BearVault with the BV One signals a promising future for backcountry safety equipment, where functionality and user-friendliness are finally being prioritized alongside essential protection.
