YETI Coolers: Super Cool & Bear Proof?

YETI was founded in 2006 by two brothers, Roy and Ryan Seiders, who were raised with a burning passion for the great outdoors and unfamiliar territory. Inspired by their teacher-turned-entrepreneur father who took them hunting, fishing, and traveling, they would spend their formative years doing just this, however one constant thing became a frustration amongst their good times – the Yeti coolers they took with them.

Unconvinced by their build quality, they often found the handles would come loose, the latches would break, and at worst, the lids would fail altogether. Knowing that there would be people in the exact same predicament as them, they said they would never put up with substandard coolers ever again, setting on a mission to build the best ice chests that the world had ever seen.

Not just limited to hunters, the appeal to outdoor enthusiasts and beach lovers alike soon became apparent. Since it does not really matter what you put inside of your cooler, only that it keeps things cold and safe for as long as possible, strength and insulation were identified as the gateway to success.

After much research and development, YETI set their cooler on the ultimate strength test – a bear. Rolling Stone magazine documented the occasion, saying “YETI had an actual real-life Bear try to open and destroy the Tundra cooler, and a 500-pound man, with neither succeeding. A virtually indestructible build”. As for keeping the contents cold, their coolers make use of Permafrost insulation – a special type of pressure-injected commercial-grade polyurethane foam, that allows for unmatched insulation power.

With Roy & Ryan having resoundingly met both of their initial benchmarks shared with like-minded adventure enthusiasts, it’s no wonder that YETI has established itself as the market leader within the world of portable coolers.

Frequently Asked Questions

Are YETI coolers really bear-proof?

Yes, YETI coolers are certified bear-resistant by the Interagency Grizzly Bear Committee (IGBC). Their rotomoulded construction and heavy-duty latches withstand direct attacks from grizzly bears during testing. For full bear-proof certification in the wild, the cooler must be locked using padlocks in designated corner slots.

How long can a YETI cooler keep ice frozen?

YETI coolers use Permafrost insulation—pressure-injected polyurethane foam—to maximise ice retention. Depending on usage, ice can last several days, with larger models keeping contents cold for over a week. Performance varies based on factors like pre-chilling, ambient temperature, and how often the cooler is opened.

What makes YETI coolers more durable than standard coolers?

Unlike traditional coolers, YETI models are rotomoulded, meaning they are made in a single seamless piece, reducing weak points. This construction, combined with thick walls, impact-resistant latches, and commercial-grade hinges, makes them virtually indestructible—even under extreme conditions.

Do YETI coolers work in extreme heat?

Yes, YETI coolers perform well even in high temperatures. Their thick insulation and freezer-grade gasket create a tight seal, reducing heat exchange. For best results in hot weather, pre-chill the cooler with ice before use and limit how often it is opened to maintain low internal temperatures.

Why are YETI coolers more expensive than other brands?

YETI coolers are built for extreme durability, superior insulation, and long-term performance. Their robust construction, premium materials, and extensive testing set them apart from standard coolers. While the upfront cost is higher, their longevity and efficiency often make them a better investment over time.
