We sell Engel coolers and can vouch for their durability and ice keeping functional. They are similar in "bear proof" models, function, durability and ice keeping time. The differences are in price and aesthetics.
Here are some of the features of the IGBC coolers:
* Interagency Grizzly Bear Committee (IGBC) Bear-Resistant
* 2″ Quality Polyurethane insulation
* Seamless polyethylene construction
* Non-Skid lid with dual corner locking holes
* Molded hand grip and convenient rope handles
* Large non-skid, non-marking feet designed to keep the cooler from sliding
* Air tight freezer gasket seal in lid
* Unique easy-open drain plug
* Cooler drains completely dry when drain plug is opened one turn
* Rugged full length self stopping hinge
* Low profile marine grade latches
* Easily secures down with most tie-down systems
I have used a 65 qt in camp with 5 hunters for 10 days, each taking turns sitting on it for the day/evening as it had the boat cushion with it. It was nice to rest your "chassis" on it after chasing elk all day!
