A carrying case makes your Bear Cache easier to transport and easier to haul up into the tree.
Expertly tested, (by bears) the Backpackers Cache will keep your dinner safe from the marauding wildlife.
While it may not replace common sense and bear-country protocols, it can deter a charging bear and allow you to escape. Cheap nonlethal insurance for you and the bears. Only to be used on attacking bears and not as a repellent around the campsite.
These bear bells easily attach to clothing or a pack.
