Vacuum-insulated coolers have been emerging on the market over the past few years, among them the precision-temperature Qool Box and the adjustable-zone Dam Cooler. Norwegian startup Oyster puts its own stamp on the genre with the aluminum-clad Tempo, a cooler so efficiently insulated, it doesn't need ice to keep food and drinks cold. That iceless design teams with a thin-walled construction to ensure that the 23-L cooler carries multiple times more beer or food than its competition.

A cooler that doesn't need ice is quite a lofty claim, but Oyster has spent the past six years perfecting its patented DLTA vacuum insulation system. It focused in on minimizing thermal bridging, optimizing vacuum core insulation and increasing interior thermal circulation. The result, it says, is that the Tempo is able to hold cold effectively enough to eliminate the need for loose ice or freezer packs. Alternatively, it can hold in heat, making it useful for transporting hot food.

Oyster explains that plastic coolers typically come with the recommendation of packing 2/3 full of ice, 1/3 of actual food and beverage. Guidelines from manufacturers like Yeti and Engel confirm the existence of the 2-to-1 ice-contents rule. So by eliminating the need for ice, Oyster effectively triples the space available for the actual food and drink you want to carry in the first place.

Cooler brands often advertise the number of cans a cooler can fit, a fairly useless spec since it doesn't factor in the ice upon which traditional coolers rely. So those cans might all fit, but they won't stay cold for very long – or you can cut that number in half or a third after dumping in the ice. With the Tempo, the 36-can estimate is an actionable number – slide in all three dozen 12-oz (335-ml) cans cold from the fridge, and the Tempo should keep them chilled for the day.

Oyster makes clear that the efficacy of the Tempo design depends on several factors, including how hot it is outside and how much contents are inside. It specifies that the Tempo will work without ice on day trips and should be packed as full as possible with cold contents for the best results. For those who plan to use the cooler longer, or don't quite trust an ice-free cooler, Oyster does package the Tempo with two ice packs that fit neatly in the bottom, designed to fit below all 36 cans.

Vacuum insulation is prized for its ability to deliver superior thermal insulation within a sleek package as compared to foam-filled plastic. A spec comparison confirms the Tempo sleeker than some of the competition, its 19.4 x 12.6 x 11.6-in (49 x 32 x 29.5-cm) exterior box dimensions giving it a total volume of 1.6 cu ft (45 L). That's well slimmer than the 2.4-cu ft (68-L) Yeti Roadie 24 hard cooler, which only holds 33 cans (no ice), or the 3.6-cu ft (102-L) 35-can Igloo IMX 24. The 12.3-lb (5.6-kg) Oyster also bests those two in the weight category, as the Yeti weighs 13.1 lb (5.3 kg) and the Igloo 16 lb (7.3 kg).

Of course, the Oyster can't win them all. In a world of thick, ultra-rugged coolers built to survive grizzly bear attacks or tumble out of a pickup bed with minimal damage, the Tempo looks quite under-armored. Oyster admits out of the gate that the aluminum cooler is not built to take on hungry bears, working around this potential shortcoming (for now) by advertising a limited lifetime warranty on its newly released first-edition coolers. It doesn't sound like it plans to extend that benefit to future editions, however.

"If a part breaks, we'll replace it. If a Tempo gets mauled by a bear, return it and we'll melt its remains and make a new one," the company promises on its website. Presumably, it will send you that new one.

Oyster's first edition replacement promise hints at the convenient, versatile and recyclable build of the Tempo. The cooler breaks down into parts without the need for tools. The included handle can swap in for the shoulder strap via hand-friendly bolts, and the top hinges can pop out to create a fully removable lid. Oyster also says the cooler is 100-percent recyclable and ready to be broken down and rebuilt into a second-life cooler or repurposed into original materials.

All that meticulous design and engineering don't come cheap, and the Tempo's US$500 price tag is high even in the high-priced world of premium coolers. That Yeti Roadie 24 costs half the price, and the Igloo is even less. It's not uncommon for coolers to cost $500 and more, but they're typically much larger at that price. However, if we're to believe Oyster's iceless claims, then the Tempo can handle some jobs of a cooler three times its size while remaining far lighter and easier to handle – and that might just be worth the price tag.

We're hoping to put Oyster's ice-free claims to the test during the upcoming Northern Hemisphere summer season (definitely with something like soda and beer, not raw chicken or other fast-perishing food), but early adopters will need to decide if the potential is worth the risk of the cooler coming up big on promises, short on results.

Why don't they state the R-value and compare that to its competitors? Alternatively, they could compare the temperature rise of a can of 4 C drink in the cooler with an exterior temperature of 20 C. That's far more useful data than "doesn't need ice".

Would come in very handy for vanlife, if it's truly as good as it says it is...

Slick video and sleek design aside, it had better perform amazingly at $500. “All day” at what ambient temperature? 50°F? 80-90°F ambient temp is where folks wish to have their cold beverages cold. For that price you’re in active cooling, low power DC compressor with internal lithium battery portable fridge turf.

Errr.......yeah........nahhh. After 6 years of development, they've forgotten that cold air falls.....perhaps the ice packs would be better in the lid? Not a fan of the garbage can look either.....harder to clean? My 40 AUD Cooler has 3 parts: tub, lid and handle. This has 41.... no wonder its $500. Days I need/want my cooler, its on the sand on the beach or in the back of the car where its twice as hot......I refuse to let a Norwegian tell me I need to operate in a cool climate and ensure I'm adhering to high loading of thermal mass for it to work! Plus i enjoy having ice in my drinks and I even repurpose the melted water to wash sand off my feet or pour over myself if its over 40deg C. Also, they haven't mentioned opening the lid losses. With an ice bath, the default temp is always 0 degC, ( it's the reference point for all scientific experiments). Drinks loaded from a fridge at best are +4 degC and with every lid open I estimate the cans would be around +10 by lunch time.......a bonus if you are in freakin' freezing Norway.......rubbish anywhere hot! This is the engineering equivalent of a Tahitian trying to design a snow mobile......best to stay in your lane occasionally :)

Bzzzzt! The whole concept fails because there is no refrigerant to keep the items as cold as possible.
Take 40-45F beverages from the fridge and put them in the 70F cooler and it'll try to keep them cool.
But at the beach, every time someone opens the lid, they fill it with 90 or 100F air while removing some of the cooler material.
Back when I drank beer, I wanted it as close to 32F as possible after playing hard in the ocean or on the beach.
That cooler starts at 42F and warms from there. Also, you can't toss a room temp sixer into it and expect it to get cold as you can with an ice-filled chest.
For that price, I'll bet 90% of the customers request their money back.

The price of ice is much less than $500.

Sounds like a wonderful product, but that price...
