Bear protection,
engineered lighter.

GramGuard is developing an ultralight bear canister for hikers who treat every gram—and every liter of pack space—as a design constraint.

Why GramGuard

Required gear should not be an afterthought.

Bear canisters are mandatory on many of the best routes in the country. They are also commonly bulky, heavy, and designed with little concern for how serious hikers actually pack and travel. GramGuard exists to address that engineering problem directly.

Weight with purpose

Reduce mass without creating a fragile or disposable product.

Useful volume

Prioritize the volume hikers can actually load with food.

Protection first

Design toward independent bear-resistance certification.

Transparent engineering

Publish real weights, test results, failures, and tradeoffs.

Development status

Built in public, without the filler.

We will share meaningful progress: design decisions, prototypes, field-test lessons, and verified specifications. No inflated claims. No lifestyle-content treadmill.
