The Denali is our premium cooler with quality fittings and additional ice holding performance. In test after test, the Denali outperforms the other ranges by at least one to two days. The latches are specially designed rubber draw down to provide excellent compression on the seal and are extra wide to provide far more durability than the common elastic pull down latches. The hinges are the best design that we have seen on any ice chest, anywhere, and are fully integrated into the cooler body and lid and have a marine grade stainless steel hinge pin making them last longer.
