- The lid and walls of the cooler are filled with a thick layer of high-quality foam insulation to create a high-performance thermal barrier.
- The cooler lid is constructed with a freezer-grade gasket made of thick rubber that seals against the rim of the cooler to prevent any air flow or loss of internal temperature retention.
- Thick rubber non-skid feet prevents unwanted sliding and shifting even in the back of a moving truck or a rocking boat
- Waterproof & Tear Resistant: All Mammoth premium soft-sided products are made with puncture and tear resistant TPU material using waterproof welded seams for a dependable, high-quality finish that lasts for years
Mammoth Cruiser and Ranger Series coolers are roto-molded for extreme durability and longevity. It takes over one hour of manufacturing to form the thick inner and outer walls of each cooler box and lid.
