Wild Ideas Bearikade Canister's are made of a lightweight carbon fiber composite. Humans can open them easily with a coin or screwdriver blade, however, animals cannot! The Expedition is the largest of these canisters and works well for extended backcountry trips. Have this canister shipped your way for your trip with this option. If interested in reserving a canister for in-store pick-up, see Expedition Bearikade Canister Rental: IN-STORE Pick-Up.
