YETI Tundra 45 Hard Cooler, Desert Tan vs RTIC 52 QT Ultra-Light Hard Cooler, Grey

The short answer

For most van and car campers, the RTIC 52 QT Ultra-Light is the better buy. By the two makers' published figures, it holds 76 cans or 51 pounds of ice against the YETI Tundra 45's 54 cans or 37 pounds, weighs about 3.6 pounds less empty (21 against 24.6), costs less, and comes with a stated ice claim of up to 7 days under RTIC's cooling tips. Its interior measures 21.25 by 12 by 12 inches, a near-rectangular box that's easy to pack.

The YETI Tundra 45 is the better choice if you camp in bear country, or if your space is tight. It's IGBC-approved as bear-resistant when locked with extra-long shank Master Lock padlocks, while RTIC doesn't list a bear certification for the Ultra-Light. It's also the smaller box outside, by about 1.6 inches in length, 1.6 in depth and 1.8 in height, and its warranty is 5 years against RTIC's 3.

Specs side by side

Sources: YETI's Tundra 45 page and RTIC's 52 QT Ultra-Light page; the RTIC warranty is from its Amazon listing. Both makers list up to three inches of insulation: polyurethane for YETI, closed-cell foam for RTIC.

Construction: rotomolded vs injection molded

This is the main design difference. The YETI is rotomolded: plastic is tumbled in a heated mold to form a single-piece, thick-walled shell, and YETI pressure-injects polyurethane foam into the walls. Rotomolded coolers have a long record of rough use on boats, truck beds and in the backcountry, and that construction is part of what earns the Tundra its bear certification.

The RTIC Ultra-Light is injection molded. RTIC says that makes it more than 30 percent lighter than rotomolded coolers of the same capacity, while keeping up to three inches of foam and an O-ring freezer-style gasket. The result, on paper, is a cooler that holds about 40 percent more cans with no ice and weighs less.

In a van, weight matters more than it does in a truck bed. You lift the cooler in and out, slide it across the floor and count it against payload. The RTIC's lower weight per can of capacity is a real advantage. If you need a container that resists a bear, though, construction and certification matter more than weight.

Edge: RTIC for weight and capacity; YETI for proven rough-use construction and certification.

Ice retention: claims and conditions

RTIC claims up to 7 days "when following RTIC's Cooling Tips". It publishes those tips: prechill the cooler half full of ice overnight or for a day, prechill the contents, pack 2:1 ice to food, layer ice at the bottom and top, close the lid quickly, avoid draining meltwater until necessary, and keep it in shade. RTIC says its hard coolers go through industry-standard lab testing but doesn't name the standard or the ambient temperature.

YETI doesn't publish a days figure for the Tundra 45. Its page says the cooler keeps contents "ice-cold even in sweltering conditions" and links to ice-retention tips covering sun exposure, ice quality and ice quantity. The Amazon listing recommends a 2:1 ice-to-contents ratio.

So there's no like-for-like number to compare. Both coolers list up to three inches of insulation and freezer-style gaskets, and owner reports for both describe multi-day ice with good habits. What the numbers do show is that the RTIC holds about 14 more pounds of ice. A larger mass of ice lasts longer in the same conditions, which is one reason a bigger cooler often outlasts a smaller one even with similar walls.

Edge: RTIC, narrowly, for a stated claim and more ice capacity, though the claim is a best case.

Space and fit in a van

Food space at 2:1. When you pack at the recommended 2:1, about a third of the interior holds food. The Amazon listing for the Tundra 45 says that's 26 cans' worth. RTIC doesn't publish a 2:1 figure. By the interior dimensions each maker publishes, the RTIC's box is roughly two-thirds bigger than the YETI's, so its food third is bigger by about the same proportion. That's our arithmetic, and it's approximate, because YETI's interior figures may describe the narrowest part of the liner.

Interior shape. RTIC's interior dimensions multiply out to about 53 quarts, matching its name. YETI's published interior measurements for the Tundra 45 multiply out to well under 45 quarts, which suggests tapered walls and a narrow floor. YETI states capacity in cans and pounds of ice, not quarts, so plan by those figures.

Footprint. The YETI is the more compact box: 25.6 by 15.9 inches against 27.17 by 17.49. For comparison, the ICECO VL35 ProS 12V fridge is 28.1 by 15.9 inches, so the Tundra fits in less floor than a 35-liter fridge and the RTIC takes about the same length with more depth. Neither cooler needs ventilation clearance.

Height. At 15.5 inches, the YETI slides under more bed platforms and cargo covers than the RTIC at 17.33. Allow extra height above either to open the lid.

Weight full. Our arithmetic from the makers' figures: about 62 pounds for the YETI with a full ice load (24.6 plus 37) and about 72 pounds for the RTIC (21 plus 51). Both are two-person carries over any distance.

Edge: YETI for small spaces; RTIC for food capacity.

Latches, drains and fittings

Both use T-latches. YETI's T-Rex latches are heavy-duty rubber, and its NeverFail hinge is a two-pin design. RTIC lists durable T-latches without naming the material on the page we read.

YETI has a single Vortex drain. RTIC has two drainage holes with a Rapid V-Drain system for draining "in any position", which helps if the cooler sits sideways in a van and only one end faces the door.

Both have tie-down slots for strapping to anchor points, non-slip feet and rope handles. YETI includes one dry goods basket. RTIC sells its basket and divider separately. RTIC lists an integrated locking system for security; that isn't a bear certification.

Edge: even. RTIC's two drains are handy in a van; YETI includes the basket.

Bear country

If you camp where land managers accept certified containers for food storage, this decides it. YETI says the Tundra is approved by the Interagency Grizzly Bear Committee when used with extra-long shank Master Lock padlocks. RTIC doesn't list an IGBC certification for the 52 QT Ultra-Light.

Certification doesn't override local rules. Some campgrounds and forests require food in a provided locker or hard-sided vehicle regardless of container. Check before you go.

Edge: YETI.

Dry ice

Both makers say these coolers are compatible with dry ice. RTIC suggests wrapping it, separating it from food and cracking the drain open as pressure relief. In a vehicle, the hazard is the carbon dioxide gas dry ice gives off as it warms. Don't carry it in a closed van or car, don't sleep in a vehicle with it, and ventilate well while driving.

Value

The RTIC 52 QT Ultra-Light costs considerably less than the YETI Tundra 45 and gives you more space. Check current prices on Amazon, since they change often. What the extra money buys with the YETI is rotomolded construction, an IGBC bear-resistant approval with padlocks, rubber T-latches, an included basket, a smaller box outside and a 5-year warranty against RTIC's 3. Owners commonly report strong resale values for used YETI coolers. If none of those matter to you, the RTIC is the better use of the money.

Which one should you buy?

Buy the RTIC 52 QT Ultra-Light if:

• You want the most food and ice space for the weight.
• You have room for a box about 27 by 17.5 inches and 17.3 inches tall.
• You don't need a bear-resistant certification.
• You'd rather spend less on the cooler and more on the rest of the kitchen.

Buy the YETI Tundra 45 if:

• You camp in grizzly country and want an IGBC-approved container (with padlocks).
• Your space is tight, or you need a cooler that fits under a 16-inch gap.
• You want rotomolded construction and a 5-year warranty.
• You want a basket included.
