YETI Ramblers are over-engineered, 18/8 stainless Tumblers, Bottles, and Colsters®, designed with double-wall vacuum insulation and a No Sweat™ Design. The Tumblers will keep your soda, beer, smoothie, or mixed drinks cold twice as long as plastic cups. The Colster is like a steel bear hug for your cans and bottles, while its Load-and-Lock™ Gasket keeps your drink in its place. The Bottles go wherever there’s a need for ice-cold or piping-hot beverages. Their Over-the-Nose™ Technology makes for easy loading, drinking, and cleaning. And their TripleHaul™ Caps are 100% leakproof and comfortable to grip.

The YETI Tundra was created to solve the age-old problem of subpar coolers failing in the field. Tired of busted latches, bowed-in lids, and melted ice, brothers Roy and Ryan Seiders set out to make a superior hunting and fishing cooler — and YETI was born.

Tundra and Roadie® coolers are rotomolded, which is the same process used to create whitewater kayaks. And we designed the coolers to keep ice longer — a lot longer — by pumping them with over twice the insulation compared to most ordinary ice chests. The result is a cooler family with a dramatic durability and ice retention advantage over most any other cooler on the market.

Tundras are great for hunting, sport-fishing, camping, boating, rafting, tailgating, paddling, and barbecuing. Oh, and beer drinking, too. There’s even the Tundra 250 and 350 for commercial uses, like oil & gas, construction, and medical industries. The Roadie is BYOB’s new best friend.

There are many variables that will affect ice retention, so this is a difficult question for us to answer. Variables that can affect ice retention include the ice quality, ice quantity, type of ice (crushed, block, cube, dry), outside environment, exposure to direct sunlight, etc. Which is to say there’s a lot you can do to affect the longevity of your ice.

Over the years, we’ve received many different reports from YETI users in the field regarding ice retention. Some customers have reported having ice after their two-week trip on the river while others have said that their “crappy brand X cooler will hold ice better.”

Because of the large number of variables, as well as the lack of an industry standard for measuring ice retention, claims that place a definite time (5, 10, 14 days) are often based on testing conditions and not real-life situations.

In the end, the Tundra offers up to 3 inches of polyurethane foam insulation, combined with a freezer-style sealing gasket. Beyond that, everything else is out of our control. But if you can minimize the negative variables that affect ice retention, YETI coolers can’t be beat.

Can I use dry ice in my YETI?
Absolutely! The thickness of the walls, coupled with the amount of insulation make YETI dry ice–compatible.

You might be surprised to read this, but YES. The same insulation and thick walls that keep the cooler cold also keep the heat.
