FAQ

How Should I Use My Hard Cooler?

🥾Coolers are great for hunting, fishing, camping, rafting, barbecuing, and beer drinking. There's no adventure this mighty ice chest can't take on.

🔧What Does Rotomolded Mean?

Rotomolding is a plastic-forming process that produces extremely durable, hollow, single-piece molds. It’s similar to how high-grade polyethylene whitewater kayaks are made.

💪How Tough Are Tundra Hard Coolers?

Our rotomolded coolers are stronger than this grizzly and this guy. They also survived battles with a slingshot, so we’d say pretty damn tough.

🐻What Does "Grizzly Resistant" Mean?

Our locked hard coolers were tested and approved by the Interagency Grizzly Bear Committee. Make sure you utilize the bear proof locks to keep the grizzlies out.

❄️How Can I keep My Ice In My Cooler Longer?

Minimise negative variables (sun exposure, poor ice quality, too little ice, etc.) and check out our comprehensive list on how to maximize ice retention here.

🧊Can I use Dry Ice?

Absolutely. The thickness of the walls, coupled with the amount of insulation make Tundra® Hard Coolers dry ice compatible.

🔥Will It Also Keep My Hot Items Hot?

Yes. In fact, our pitmasters use them to hold hot, fresh barbecue. The same insulation and thick walls that keep the cooler cold also keep the heat.

🧽Is It Easy To Clean?

Yes. We recommend using soap and warm water. If you need a heavy-duty cleaning, use a 6:1 solution of warm water and bleach with a sponge or mildly abrasive rag.
