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 Blazer is a mid-sized canister (750 cu in) which falls between the smaller Weekender canister (650 cu in) and the oversize Expedition (900 cu in). Have this canister shipped your way for your trip with this option. If interested in reserving a canister for in-store pick-up, see Blazer Bearikade Canister Rental: IN-STORE Pick-Up.
