Unless you’re toting a great cooler, your people will never take you seriously. Sorry, but those are the rules. The neighbors will laugh. The boaters will smile politely. Your kids might even toss you a cold one without an audible grunt. But no matter how much ice you cram into a cheap cooler, it just won’t get the job done on a hot Texas day.

Remember the last time you opened your cooler to pluck a cold drink out of the ice and saw a flotilla of cans bobbing, but not a cube in sight? You need an upgrade. Like the rest of Ninja’s brilliantly engineered products, its 30-quart FrostVault cooler rules the sweet spot.

A good cooler will keep your food and drinks chilled for hours. A great cooler will hold the cold for days. That’s why we’re smitten with Ninja’s FrostVault. It’s built with nearly 3 inches of insulation, a durable exterior and a lockable lid to keep your stuff secure.

The sleek design and robust build mean it can withstand the rough and tumble of any adventure. The nonslip feet ensure it stays put, whether on a boat deck or a sandy beach. A removable divider can split the interior box in half, making it easy to keep the kids’ drinks apart from the hooch. And a clever slide-out drawer provides a separate dry zone below the ice box to keep its contents at food-safe temperatures (under 40°F) for days.

We filled our 30-quart test cooler with cubed ice and a full case of beer then left the cooler outside during a heat streak last month. The ice slowly melted into slush over the next two days, but it didn’t entirely disappear until deep into the third day. We loved the leakproof cooler’s hefty latch, which kept the lid tightly sealed, and the rotomolded handles that made the cooler easy to carry, assuming you’ve kept up with arm day at the gym.

We packed the FrostVault with a case of drinks and ice, filled the drawer with cold foods for the grill like burgers and cheese, then headed somewhere fun. The following day, our icy-cold stuff was still icy cold, and the dry goods remained dry and safely chilled.

Should you need to haul the box beyond the boat dock or backyard and deep into the great outdoors, Ninja cleverly built in two slots for padlocks or zip ties to lock down the lid. That should keep the cooler’s contents safe from bears and raccoons, but as any parent will caution you, curious kids are an entirely different animal.
