Used only for a few days on a guided trip (I was the guide). You'll need something like this if you plan to backpacking in Rocky Mountain National Park, The Maroon Bells/Snowmass Wilderness as well as many other Wilderness Areas + National Parks in the country.

Features:
* Durable polycarbonate construction keeps the weight light and the inner volume high
* Large rainproof lid features a snapping bump/tab locking mechanism and screws on and off easily without the use of tools
* Dimpled exterior keeps tie-down straps from shifting and eliminates the need for a carrying pouch
* Translucent vault makes finding your meal selection easy
* Container helps suppress strong odors from food, sunscreen, insect repellent, soap and toothpaste, lessening the chance of bear vs. human conflict
* Hand wash in warm water with a mild dishwashing detergent
* With the lid fully closed the BearVault also makes a great camp seat
* This BearVault model has approval from both the Sierra Interagency Black Bear Group and Interagency Grizzly Bear Committee
* Store BearVault at least 100 yards downwind of campsite, preferably in the shade to keep contents cool
