Reusable ice packs contain special chemicals that keep things cold, whether for shipping refrigerated items or stocking your cooler for a day at the beach. 

We researched and tested dozens of ice packs, judging them on effectiveness, longevity, and value. Our top choice, Cooler Shock Reusable Ice Packs, do the job of 18 pounds of ice to provide long-lasting cold with minimal sweating. 

Here are the best ice packs for coolers.

The ultimate summer entertaining requires cold drinks on constant standby–all throughout the day. If you are packing up a large cooler for a day in the woods or a night of car camping, our top pick is a set of the extra-large Cooler Shock Freeze Packs. These reusable packs are affordable and ridiculously effective at keeping cold items cold.

These packs can replace about 18 pounds of sweaty, dirty ice and they are incredibly easy to use. They are shipped flat with a powder inside that transforms into a gel when mixed with water. Simply fill the bag via the screw cap with water, place it in your freezer for about 24 hours and the non-hazardous packs will be frozen and ready to go. The packs are 10 x 14 inches so they are perfectly sized for high-capacity coolers, but our tester was surprised at how much space the three packs took up in her home freezer while prepping for the next day's outdoor activities. However, she found that the ice packs did get extremely cold (more so than any other pack she'd used before), and they kept her frozen fruit, seltzers, and beer cold for 22 hours while the cooler sat outside.

If you've got a large cooler and are planning on a long day of summer activities, this set of ice packs is your best choice.

Weight: 7.05 ounces | Dimensions: 10 x 14 x 1.5 inches | Type: Ice pack | Reusable: Yes

What Our 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 Cooler

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 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. 


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.

  • How do you make ice packs super cold?

    To make sure that your ice packs are super cold, be sure to follow package directions to freeze them completely before using. You can help keep them cold by chilling your cooler with ice before filling it, and lining the cooler with aluminum foil. Chilling or even freezing items that you plan to pack, such as bottled beverages, will help the inside of the cooler to stay cool and your ice packs to stay frozen longer.

  • How many ice packs do you need for a cooler?

    That depends on the size of your cooler and how much food and how many beverages you are trying to keep chilled. Ice packs come in varying sizes and formats, from small enough to fit into a lunchbox to large enough for a cooler full of drinks and snacks to feed a crowd. In general, you will want to aim for a 2:1 ice to food or beverage ratio to ensure that your items will stay cold.

  • How long do ice packs keep a cooler cold?

    It depends. Some ice packs freeze quickly for short-term uses such as picnics and in lunchboxes, while others take longer to freeze solid, but will keep the contents of your cooler chilled for more than 24 hours. Be sure to read the label before buying to make sure you are choosing the appropriate ice packs to meet your needs. Another tip for keeping your cooler cold is to pre-chill it with ice before packing, which will help the contents stay longer than if you packed a warm cooler pulled straight from a hot attic, car trunk, or garage.
