10 Reviews: Best Ice Packs for Large Coolers (Apr 2024)

We recommended the Igloo Maxcold Natural Ice Sheet if you have a large cooler and require an ice pack that wraps twists, and lies flat. The huge sheet features 88 cubes that keep meals and beverages cool for several hours. The ice sheet is made of durable, reinforced plastic and is sealed for safety. It is filled with a proprietary gel that cools items quicker than ice and keeps them colder for longer. Plus, it’s super affordable!

These are so nice to either cut to a desired size or bends around stuff in a large cooler. Even when a couple bubbles pop there's plenty to keep my stuff cold.

These ice packs, like the others on our list, are slim enough to fit in your cooler without taking up too much room. They are also quite lightweight, which is ideal if you like to camp as light as possible. Though they may be little in size, they deliver a huge punch and will keep your food and beverages cool for hours. Additionally, the Healthy Packers Ice Packs are constructed entirely of non-toxic components.

I purchased these for a trip we were taking and needed to keep a large cooler cold. They worked perfectly. They fit into small places that large packs cannot. They are thin so I worried that they wouldn’t stay cold but they Lasted for our 7 hour car ride

The Healthy Packers Long Lasting Ice Pack is a terrific alternative when you need to keep your beverages chilled and don’t want them rolling about inside your cooler. The ice packs’ curved shape keeps bottles and cans in place, making them ideal for anything from tailgate parties to breast milk cooler bags. The set of two contoured cooling packs is constructed of non-toxic, BPA-free plastic that is safe to use near food and keeps items cold all day.

Bought this for my husband’s lunch cooler. He says it stays frozen all day. He loves it! Highly recommend

This one is designed for small coolers, but since it has great cold power, you can easily add additional pieces to your larger cooler. The slim ice packs are barely half an inch thick and are ideal for lunch bags, diaper bags, or fitting into coolers already full of food and beverages. When accidents happen, the hard plastic exterior is simple to wipe down and clean, and the ice packs keep cold for hours.

Very nice! I have a large, insulated lunch bag from REI. the slim shape of these packs allows me to put them on sides and the top of my lunch. I'm also amazed at how long they stay frozen. I have some very long work days and need something that will stay cold a long time. These little packets are a big bang for the buck.

Cooler Shock ice packs have a large surface area and a low freezing point, therefore they have a lot of chilling power. When frozen, each pack weighs 5 pounds and replaces around 6 pounds of ice. Its slim shape enables it to easily fit into both coolers and freezers. The freezer pack has a ribbed surface that distributes the gel cooling agent evenly while increasing surface area. The packs will keep the contents of a large cooler cold for an entire day.

The X large is perfect I have 4 now.Hold on buying ice for keeping beverage cold. Fits nice in all size coolers.

This ice pack is a useful companion for your coolers and terrific addition to your outdoor adventures. It quickly chills the contents of your cooler and keeps it fresh for long periods of time. It’s custom-made to accommodate Pelican coolers and has a UV-protective exterior. It also has a one-of-a-kind dual-grip design for comfortable handling. This reusable ice pack is also BPA-free, non-toxic, and FDA-approved for food use, making it safe for any use.

It's large. I love it

We recommend the Yeti reusable pack for an ice pack that will withstand a harsh voyage in your cooler. The break-resistant cooler pack is filled with a specially designed liquid that is colder than ice and swiftly cools the stuff surrounding it. The ice pack can drop to -2 degrees Celsius and remain there for hours, however, bear in mind that the oversized pack weighs a staggering 4 pounds, so keep that in mind when determining who will carry the cooler to the destination.

The absolute best ice pack I've ever had!! I work an average of 10-12hrs a night with a 1hr commute each way. Had one night I worked almost 18hrs. It lasted the whole time, kept everything in my Yeti Roadie cold with only a small amount of melt down from the ice pack.

Cooler Shock 3x screws cap fill and seal cooler freezer packs are extra-large packs ideal for carrying a large cooler for a day in the woods. It’s reusable, slushy, and cold—colder than ice at 18 degrees Fahrenheit. These extra-large cooler ice packs are equivalent to around 20 pounds of ice. So there will be no filthy water in your cooler! Simply fill them with water via the screw top, set them in your freezer for approximately a day, and they’ll keep your drinks cool for up to 48 hours!

[...] I use 2 large, one on bottom of a soft cooler bag then my drinks and one on top. It’s lasts about 8 hours on a beach in the sun( My cooler is probably not the best). If you add ice it will last even longer. Easy to fill, just 1 time, freeze for a day and your good to go.

Cooler Shock ice packs have a large surface area and a low freezing point, therefore they have a lot of chilling power. When frozen, each pack weighs 5 pounds and replaces around 7 pounds of ice. The freezer pack has a ribbed surface that distributes the gel cooling agent evenly while increasing surface area. Don’t be concerned about a spill! Even on the bumpiest trips and excursions, the screw top on our ice packs for cooler accessories remains tight.

I have been using it for months now. I put all 3 in my large cooler and it makes the ice last 2 days longer. I put mine it a large freezer that can get to 5 degrees Fahrenheit.

To get the most out of this Ice pack, use a hydration setup that includes submerging it in water, followed by some firm squeezing to let out any trapped air. Besides that, the Techni ice can last for up to 14 hours so it’s great to bring on your outing. But it isn’t the only thing that separates it. In comparison to typical ice packs, Techni ice has a very low freezing point. What’s more, this ice pack can be heated up. It will keep your food warm for picnics.

I have used Techni-ice sheets in the past and was very pleased. I then purchased a similar product but was not as pleased. I am happy to have the Techni -ice again. I use them for transport of frozen foods during travel and love them.
