• Rotomolded Construction: This manufacturing process makes the cooler virtually indestructible and armored to the core, ensuring it can withstand the toughest outdoor conditions without cracking or bowing.
• PermaFrost™ Insulation: Pressure-injected commercial-grade polyurethane foam is utilized in the walls and lid to provide exceptional thermal resistance and unmatched ice retention for days.
• FatWall™ Design: The extra-thick walls hold up to three inches of insulation, creating a massive thermal barrier that keeps your contents ice-cold even in sweltering temperatures.
• T: Rex® Lid Latches: These heavy-duty rubber latches are built with patented technology to ensure they never bust, providing a secure and reliable seal that keeps the heat out.
• NeverFail™ Hinge System: An interlocking two-pin design prevents the hinge from ever breaking, offering long-term durability and a self-stopping lid for easier access to your provisions.
• Handwashing Recommended: To best preserve the high-quality finish, integrated components, and overall longevity of the cooler, we recommend handwashing only.
