In detail: Ninja FrostVault 28 litre hard cooler with Dry Zone
Ninja, part of the SharkNinja group already known for its air fryers and multi-cookers, is taking on the premium passive cooler market with the FrostVault 28 litre. Up against established names like Yeti and Dometic, it leans on a simple idea rarely executed this well: genuinely keeping dry food separate from the ice, rather than piling everything into a single compartment.
That separation takes the form of a built-in drawer, the Dry Zone, which draws on the cold generated by the cooler to hold a fridge-like temperature, under 4.5°C (40°F), for several days, without ever having to open the main lid or dig a hand into melted ice water. Cheese, cold cuts, fruit or sandwiches stay cool and dry, a genuine comfort upgrade for a picnic, a barbecue or a long car journey.
On capacity, its 28 litres hold up to 48 cans with no ice, or 26 cans once ice is added, comfortably enough for a group outing. Ice retention is claimed at up to 5 days, thanks to a tough rotomoulded build and up to 7cm of insulation, figures measured under controlled lab conditions and worth tempering against real sun exposure and how often the lid gets opened.
The cooler also gets finishing touches built for heavy use: durable moulded carry handles, a lockable lid with a premium one-handed latch system, and a structure sturdy enough to double as a seat at an impromptu match or an evening by the water. It's available in Slate Grey or Cloud White, backed by a 5-year manufacturer warranty once registered.
A couple of things worth knowing before buying: at 9.2kg empty, it's not the lightest in its class once loaded, and its price sits above entry-level passive coolers without quite reaching the absolute premium tier of a Yeti Tundra. For anyone after a genuine dry food and ice separation without the hassle, the Ninja FrostVault 28L remains one of the most complete options on the market today.

Comparison
At around £200 to £280, the Ninja FrostVault 28L regularly comes up against the YETI Tundra 35, the long-standing benchmark for rotomoulded passive coolers, in searches like "Ninja FrostVault vs Yeti". Here's how the two compare, based on both manufacturers' published specifications.
| Criteria | Ninja FrostVault 28L | YETI Tundra 35 |
|---|---|---|
| Capacity | 28L, 48 cans with no ice | 39 cans with no ice (13.2kg of ice) |
| Ice retention | Up to 5 days claimed | Several days claimed |

In short, the Ninja FrostVault 28L innovates with its refrigerated Dry Zone drawer, which genuinely keeps dry food apart from the ice, a real everyday advantage over the Yeti's simple removable basket. The Tundra 35 leans on its long-standing reputation and slightly thicker insulation, at a noticeably higher price.

Our tester's verdict: Gilles Caron
I took this FrostVault out on three trips, including a weekend of fishing and a festival under full sun, packed the night before with ordinary bagged ice. The rotomoulded build inspires confidence straight away: thick walls, a lid that snaps shut cleanly on the premium latch system, and moulded handles that don't dig into your hand even when it's full. The real standout is the Dry Zone drawer: keeping cheese, cold cuts or fruit in there without ever dunking them in melted ice genuinely changes how you use a cooler day to day, no more wrapping everything in plastic bags. After a little over four days in the shade and then full sun in the afternoons, there was still unmelted ice left, a solid result even if it fell just short of the claimed 5 days in real-world heat. The lockable lid is a nice touch for strapping it down in the boot without worrying it will pop open. The one downside: at 9.2kg empty, it's not the lightest in its class once loaded, and the price sits at the upper end for a non-premium passive cooler. For anyone who genuinely wants to keep dry food and cold drinks apart without the hassle, this is one of the most complete solutions on the market right now.
