Can You Put Dry Ice in a YETI Cooler? Yes, With 3 Rules

Quick answer: Can you put dry ice in a YETI cooler? Yes, if it’s a hard cooler. YETI says dry ice is recommended in its Tundra and Roadie hard coolers and its TANK ice buckets. It is not suitable for Hopper soft coolers, V-Series coolers or Rambler drinkware. Wrap the dry ice, keep the cooler somewhere ventilated, and handle it with gloves.

The soft cooler part is the one I’d underline twice, because a Hopper looks rugged enough to handle anything and people reasonably assume a cooler that tough can take whatever a hard cooler can. It can’t. YETI’s Hopper FAQ doesn’t hedge: using dry ice in a Hopper “will cause the airtight vessel to explode.”

So check which cooler you own before you buy a single pound. Seriously.

Why Can a YETI Hard Cooler Take Dry Ice?

Dry ice is frozen carbon dioxide at about -109°F. It doesn’t melt into water. Instead it turns straight into CO2 gas, a process called sublimation, and that gas has to escape somewhere, which is the whole reason the type of cooler matters so much here.

YETI says two things make its hard coolers work with it. The thick walls and heavy insulation handle the extreme cold, and the coolers are designed to release pressure. That second part is why YETI admits its hard coolers aren’t 100% leakproof if you tip them on their side.

A Hopper is the opposite. It’s built to be airtight and leakproof. Great for a kayak, terrible for a block of sublimating CO2.

Can You Put Dry Ice in a YETI Cooler? Model by Model

YETI product	Dry ice?
Tundra hard coolers	Yes
Roadie hard coolers	Yes
TANK ice buckets	Yes
Hopper soft coolers (all)	No
V-Series	No
Rambler drinkware	No

If your model isn’t on the list, my advice is simple. Check its owner’s manual or ask YETI before you try it, because guessing wrong with a sealed container and a block of CO2 is not a mistake you want to learn from in the back seat of your car.

How Much Dry Ice Do You Need for a YETI Cooler?

YETI’s rule of thumb: one 10-inch, 10-pound block of dry ice for every 15-inch length section of a Tundra, Roadie or TANK. Packed that way, it says everything stays frozen, including any regular ice, for at least 24 to 48 hours.

YETI also says dry ice has almost three times the cooling power per pound of regular ice. That’s the real appeal, in my view. You haul less weight for the same cold, which matters when you’re carrying a loaded cooler from the truck to a hunting camp or down to a boat ramp.

How to Use Dry Ice in a YETI Safely

These steps follow YETI’s own instructions:

1. Wear gloves. Leather or cloth gloves work; oven mitts or a hand towel will do in a pinch. Bare skin on dry ice causes freezer burn.
2. Wrap each block in several sheets of newspaper before it goes in.
3. Put it on top if you can. YETI says dry ice lasts longer packed on top of the food, though many people put it on the bottom for convenience.
4. Mix in regular ice if you like. Cubed or block water ice works fine alongside it.
5. Fill the air gaps. Less empty space keeps dry ice frozen longer. Regular ice is a good filler.
6. Keep it cold and covered. Park the cooler in the coldest spot you can find, and throw a blanket or sleeping bag over it.
7. Ventilate. Store and transport the cooler where air moves. This is the step I’d never skip.

And keep dry ice away from small children. YETI calls this out specifically, and I’d add pets to that list.

The Ventilation Rule, Explained

Here’s why step 7 matters. It’s chemistry.

As dry ice sublimates, the CO2 gas pushes oxygen out of the surrounding air. YETI says that in a closed space, like a sealed car, it can cause shortness of breath and, in extreme cases, loss of consciousness.

In practice, that means cracking a window on a long drive. Don’t leave the cooler in a closed car with people or pets inside. Don’t store it in a tiny closed room either.

If anyone feels short of breath, dizzy or gets a headache around dry ice, get them into fresh air right away. Call 911 if symptoms don’t clear quickly.

Can You Fly With Dry Ice in a YETI Cooler?

Sometimes, with limits. The FAA allows up to 2.5 kg (5.5 lbs) of dry ice per package and per passenger when it’s used to pack perishables, and airline approval is required.

The package must not be airtight, and in checked bags it must be marked “Dry ice” or “Carbon dioxide, solid” with the net quantity. My take: a YETI hard cooler’s pressure-release design fits the not-airtight rule on paper, but your airline still has the final say. Call first.

Exceptions and Common Mistakes

• Hopper soft coolers: never. Not even a small piece.
• Drinks right next to the block: dry ice is meant to keep things frozen, so expect anything touching it to freeze solid.
• Bare hands: use gloves every time, including when you unpack.
• Closed cars and tents: ventilation is non-negotiable.
• Expecting it to be leakproof: a YETI hard cooler vents, so don’t lay it on its side with meltwater inside.

Frequently Asked Questions

Can You Put Dry Ice in a YETI Hopper?

No. YETI says Hopper coolers are not compatible with dry ice, and that using it will cause the airtight vessel to explode. Use regular ice or ice packs in any soft cooler, and see how to clean a YETI soft cooler for its care rules.

Will Dry Ice Crack or Damage a YETI Tundra?

YETI lists the Tundra as dry ice-compatible, crediting its thick walls and insulation. I’d still follow the amount and wrapping guidance and keep it ventilated.

Can I Mix Dry Ice and Regular Ice in a YETI?

Yes. YETI says you can use dry ice together with cubed or block water ice, and regular ice is a handy way to fill air gaps around the dry ice. For how long a full load lasts, see how long a YETI cooler holds ice.

Should I Put Dry Ice on the Top or Bottom of a YETI?

Top lasts longer, according to YETI. Bottom is fine if it’s easier to pack, as long as the block is wrapped in newspaper.

Is Dry Ice Safe in a Car?

Only with ventilation. CO2 from dry ice can build up in a closed vehicle and displace oxygen, so keep fresh air moving and never leave people or pets in a closed car with it.
