Best Ice Packs for Coolers

The Spruce / Chloe Jeong

Sunscreen, your beach towels, and your kids' floaties? Check. A good cold beer and a classic piece of outdoor furniture? Got it. Bug spray? Of course! Ice packs? How'd you forget?! Just like any other summertime essential, reusable ice packs keep your cooler chilled for longer than ice without the mess of melted ice at the end of the day. But before you start shopping, you have a few decisions to make. You want to make sure your ice pack is big enough to fit your cooler while still leaving room for your food and drink. In addition to size, you'll also want to think about whether you want a flexible ice pack that can hug your items as it melts or a hard-sided, more durable option.

Once that's decided, consider how you'll use the ice packs. Some packs take a day or two to freeze solid, but can keep a cooler chilled for more than a day. Others freeze quickly, but also melt quickly, so they're best used for short-term uses, like lunch boxes or picnics.

Here, the best ice packs for coolers of all sizes.

What Testers Say

"The three-layer bags are designed to absorb and transfer energy and due to the bag’s large surface area, it can distribute an incredible amount of cooling power. At 18 degrees, the gel material in these packs gradually changes from a solid to a liquid, making them colder and more effective than ice."—Sage McHugh, Product Tester

What to Look for in an Ice Pack Coolers

Freeze time

How long an ice pack takes to freeze, as well as how long it stays frozen, are important factors to think about when shopping. Consider how frequently you plan to use yours and on what type of occasions you'll be using it.

Size

Size is also something you should consider. Do you want big ice packs to cool a large cooler of food or smaller versions you can use for lunch boxes and other containers? Also, think about how much freezer space you have and how much of it you’re willing to give up to hold your ice packs. 

Flexibility

While an ice pack’s primary job is to keep the items in your cooler cool, the amount of flexibility may determine how you use the packs. Hard sided packs are good for keeping the temperature down, but may not fit if you have awkwardly shaped items in your cooler or need lots of direct contact with items like drinks. Soft sided packs won't be as durable as those with hard plastic casing and could be punctured or burst as they melt.
