Bear canister or bear proof food containers can be hard to find at local stores while traveling. If you are really into backpacking then you might find the need for this item. It's either this - or find the baby bear hanging from a cracking tree limb trying to reach you food, hanging out of reach. Bear resistant containers are nearly fool proof. Remember, a bears sense of smell is 7 times greater than humans. If the bear strolls off with this item, you might need to search for a while to find it in the morning.
