Quick Answer
You can't use a regular cooler for bear-proofing because they are not designed to withstand the pressure of a bear's attempts to access the food inside.
Choosing the Right Cooler
When it comes to bear-proofing, you need a cooler that is specifically designed for this purpose. Look for coolers that are certified by organizations such as Interagency Grizzly Bear Committee (IGBC) or the National Park Service. These coolers have been tested to withstand the pressure of a bear attempting to access the food inside. For example, a popular option is the YETI Tundra, which is certified by the IGBC and can withstand a minimum of 93 kg (205 lbs) of pressure.
Inspecting the Cooler
Before purchasing a bear-proof cooler, inspect it for any weaknesses or vulnerabilities. Check the latches, hinges, and seals to ensure they are secure and can withstand the pressure of a bear. Also, inspect the material and construction of the cooler to ensure it is durable and can withstand the elements. For example, a cooler made from high-density polyethylene (HDPE) or polypropylene (PP) is a good choice because it is durable and resistant to scratches and cracks.
Proper Usage and Maintenance
Even with a bear-proof cooler, there are still steps you can take to ensure your food remains safe from bears. Always store the cooler in a secure location, such as a bear-proof campsite or a designated bear-proof storage area. Also, make sure to clean and maintain the cooler regularly to prevent the buildup of bacteria and other contaminants that can attract bears. For example, wash the cooler with soap and water after each use, and dry it thoroughly to prevent moisture buildup.
