The BearVault BV ONE is the world's first adjustable bear canister — a patented telescoping design that expands to hold a full food supply at the trailhead, then collapses as you eat, eliminating dead air in your pack as the trip progresses. At just 1 lb 15 oz (895 g), it has more internal volume than the BV450 with 2 oz less weight, fits 1–4+ days of food, and opens effortlessly with soft-touch buttons — no tools, no awkward lid wrestling with cold or tired hands. IGBC Certified (#255500), accepted in most National Parks and Wilderness Areas across North America.

The First Bear Canister That Shrinks as You Eat

Traditional bear canisters occupy the same space on Day 4 as they do on Day 1 — wasted volume that throws off pack balance and limits your options for organizing gear. The BV ONE solves this with a telescoping design that lets you twist the canister to any height between 5.6 in collapsed and 8.5 in expanded. Start full, stay organized, and compress the canister each day as your food supply shrinks. Your pack stays tighter, more balanced, and more efficient for every mile after the first.

More Volume. Less Weight.

The BV ONE's 8.3 L (505 cubic inch) expanded capacity beats the BV450 by over a litre — enough to carry 1–4+ days of food for one person, or squeeze a 6-day trip by keeping Day 1 food accessible during the hiking portion of your first day. When collapsed, it drops to 4.65 L (282 cubic inches), roughly the size of a traditional 3-day canister. The weight of 1 lb 15 oz (895 g) makes it lighter than the BV450 despite the larger maximum capacity — the adjustable design avoids carrying unnecessary structure.

Center Access and Smart Organization

Unlike top-loading canisters where everything ends up in a pile, the BV ONE opens from the center, splitting into two halves with the press of the soft-touch buttons. This gives you immediate, clear access to all your food without digging to the bottom. An optional center divider (doubles as a camp frisbee) lets you split the interior however works best — snacks and meals, food and trash, your food and your dog's food. Two halves, no overthinking.

Easy-Open Buttons — Even With Cold Hands

BearVault replaced the traditional lid and tab system with soft-touch buttons and self-cleaning smooth threads designed specifically for real backcountry conditions. Opening the BV ONE requires no tools, no coins, and no significant grip strength — which matters when it's below freezing, your hands are exhausted, or you just want to get to dinner without a struggle. The threads are self-cleaning, so dirt and grit from the trail don't make the lid harder to open over time.

IGBC-Certified Bear Protection

The BV ONE carries full IGBC Certification (#255500), verified through real-world testing against grizzly bears. It meets the legal food storage requirements for most National Parks and Wilderness Areas in North America, including Yosemite backcountry zones, the Sierra Nevada, and regions managed by the USFS, NPS, and BLM. Note: The BV ONE is not currently on the approved product lists for Yosemite Valley, Sequoia, or Kings Canyon, which have not updated their lists to include recently released products. Check specific park requirements before your trip.

Doubles as a Camp Stool

Like all BearVault canisters, the BV ONE is built to handle being sat on. Expand it fully, lock it, and it functions as a sturdy camp stool — one less thing to carry. The rugged polycarbonate shell is reinforced at the areas bears chew most, so it can take the abuse of both wildlife encounters and regular backcountry use.
