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 Scout is the smallest of the canisters that work for overnight trips or shorter trips in the backcountry. Have this canister shipped your way for your trip with this option. If interested in reserving a canister for in-store pick-up, see Scout Bearikade Canister Rental: IN-STORE Pick-Up.
