Otterbox Venture 45

The Otterbox Venture 45 won our top spot.

Best Overall
OtterBox Venture 45

Cold hard facts: 45-quart capacity; includes dry storage tray and bottle opener; bear-resistant; limited lifetime warranty.

Out of all of the ice coolers that we tested, the Otterbox Venture 45 kept its cool, and had great versatility and usability. Through our testing, it was able to keep temperatures under 40°F for almost five days, 20% above average. We found the latching lock system easy to use, and once engaged nothing leaked out no matter how much we shook the unit. In addition, we appreciated the added mounting system on the front and back for any attachments that you would like to place (eight in total). The way the handles are built into the body of the cooler made us feel confident when moving the Venture.

When you decide to set up camp, you can use the side handles to tie-down the cooler for extra security. Even without that though, we found the rubber feet to be well designed and sturdy on their own. When loaded with ice and drinks, Venture didn’t budge an inch after a swift kick from our boot, where lesser coolers tipped over. After the fun was done, we popped the drain and watched all the melted ice drain through the sloped interior.

If we had one complaint, it would be that the price is a bit high for anyone who doesn’t go on multi-day fishing or camping trips.

Ozark Trailer

We found the Ozark Trail to have the right balance of value and performance.

Best Value
Ozark Trail 52-Quart Cooler

Cold hard facts: 52-quart capacity, includes wire basket, bear-resistant, limited five-year warranty.

The Ozark Trail found its way to be our best value pick. It has a built-in fish ruler, four cup holders, a bottle opener, a threaded plug, and T-handles. It also comes with a removable wire basket. During our tests, the Ozark Trail stayed cool a little over four days before it hit the 40°F, the point at which the FDA says meat will spoil. Based on all its extra features, we think this cooler is perfect for anyone looking for a leisurely trip—think of all those cupholders! We really mean leisurely—this cooler lacks any built-in method for mounting it to a truck or boat.

Because it didn’t ace the temperature retention tests and can’t handle being in choppy situations, like the Venture, it did not get the top spot. However, given its low price, we think it’s a solid value.

Lifeproof

The Lifeproof backpack cooler won the top spot for the best portable cooler.

Best Portable
LifeProof Backpack Cooler

Cold hard facts: 18- to 24-can capacity; includes ice pack, bottle opener, two pockets, and water bottle holder.

At first glance, we thought the Lifeproof was just a backpack. However, after spending a week testing it, this portable cooler impressed us with its design. The flat bottom is a great design choice that allows the backpack to sit upright, allowing you to take a break from carrying it without risking a spill. The padded back and shoulder straps kept us from feeling the weight on our shoulders while we did laps around our lab. And as much as we liked the cooler, the Lifeproof did not forget that it was a backpack at heart, providing plenty of pockets for items that don’t need to be chilled.

For example, a pocket on the side provided easy access to a water bottle. There are two side straps that allow for attaching any items you want. Lastly, we appreciate the inclusion of an ice pack, because who has time to buy ice?

During our temperature tests, the Lifeproof lasted two days before it reached the 40°F mark, making it perfect for short trips. Anything beyond that, and you need to rethink your expectations of a portable cooler.

How We Tested

The Testers

Hi, Kyle Hamilton, Jon Chan, and Dr. Julia MacDougall here! We’re the testing team at Reviewed, which means we designed and implemented the experiments involved in this article. For ice coolers, we were most concerned about performance, portability, and price.

The Selection Process

When searching for the right cooler or ice chest to test, we made sure to include some of the most popular units on the market. We also knew that we wanted to include a variety of coolers, ranging from hard to soft, portable to heavy-duty. In addition to types, we took care to find coolers available at a variety of retailers, including Amazon, Home Depot, and Walmart.

The Tests

Ease of use

In some cases, coolers that performed well did not win top spots because they were difficult to use.

After being assigned this project, we knew the first thing we wanted to test was how long each cooler could maintain a temperature. To do this, we filled each cooler, regardless of size, halfway up with ice. We then placed the ice coolers into our humidity-controlled lab space to make sure we always had a consistent ambient temperature of 72°F and 50% relative humidity. To track the temperature of each cooler, we placed two sensors that recorded the temperature over time so we could know when the internal conditions reached over 40°F—the point at which meat becomes unsafe to eat. One sensor was placed at the bottom of the cooler, wrapped inside a ground pork meatball. We placed the other sensor on top of the ice and removed it daily both to get readings and simulate normal use. The test ended when all a cooler visibly contained no ice.

Portability testing

The best way to test portability is to carry a cooler around.

The next tests involved portability, build quality, and aesthetics of each ice cooler. We design the portability test to be pretty straight forward: Fill the cooler with water and walk around with it. We went up inclines, took sharp turns, and trotted around the lab. Exhausted and out of breath, we then tested to see if they were leakproof by tipping each cooler to see if the water would come out. Emptying each model of water gave us a chance to look into the design and features. Lastly, we filled each cooler up with soda cans to see how many cans you could fit into them and compare it to the claimed capacity of the ice coolers.

Extra Features

Nowadays, coolers are more than just plastic boxes. We tested all the extra features to see if they worked.

What You Should Know About Coolers

How Much Ice Should I Use?

Ice

You should use a 2-to-1 ice-to-food ratio.

According to Popular Mechanics, you should use a 2-to-1 ratio of ice to items being cooled. For example, if you were cooling a gallon jug of milk, you’d use two gallons of ice to keep it cool. However, the more ice the better the food preservation.

How Can I Make My Cooler Last Longer?

Shade

To maximize your cooler's performance, keep it locked up tight and in the shade.

Pre-cool your cooler: If you’re storing your cooler in a hot garage, bring it inside so it can get up to room temperature, that way you’re not wasting energy cooling down a hot plastic box.

Avoid using ice that's already melting: A bag of ice that's dripping water is already too warm to keep a cooler at the correct temperature

Don't drain out the excess water: Cold water helps insulate the ice you add in.

Can I Use Dry Ice in a Cooler?

Dry ice can be used in most coolers. It’s way colder than normal ice and can keep ice cream and meat frozen. When it evaporates, it leaves no puddles to clean up. There are some disadvantages. Dry ice melts at an alarming rate, about 5-10 pounds every hour depending on how often you open the cooler. It also someone dangerous to store indoors, as it is constantly outputting carbon dioxide.

Are Coolers With Wheels Worth It?

You may have noticed that none of the coolers we tested have wheels. After doing some extensive research, we decided not to include any rolling coolers. The milage people get out of wheeled coolers varied too much for our liking. On the lower end of the price spectrum, wheels and axles are a major point of failure, one of the first things to go on a cooler. Premium coolers with sturdy wheels and long warranties can go for over $400, a little too rich for our blood.

However, if you’re dead set on getting a cooler with wheels, we’d suggest thinking of your cooler like a piece of luggage rather than an icebox. Look for a unit that has a comfortable handle that can extend comfortably to your height. For the wheel themselves, the bigger the better. Bigger wheels spread out the wear and make for a smoother experience.

What Should You Look for in a Cooler for Camping?

It all comes down to how long and how far you’re going out. For trips that are less than a day, a portable backpack cooler is perfect. Just keep in mind that backpack coolers work better with ice packs than loose cubes. Once that ice melts, the sloshing will make the backpack more unstable.

If you’re heading into the backcountry, you’re going to need something more robust. The coolers that keep hot air out the best typically have T-handles and are difficult to open because of how well they seal shut. Not only do you want a unit that’s well-insulated, but you also want one that keeps the scent of your supplies away from bears and other predators.

When packing a cooler to preserve food for more than a day, you should use a combination of chunks and chips of ice. Chips help with immediate cooling and chunks are for the long haul. Also, be sure to store your cooler in the shade away from direct sunlight.


Other Coolers We Tested

Rtic 45

Cold hard facts: 45-quart capacity, includes no-slip feet and multiple drains, limited lifetime warranty.

In our testing, the RTIC cooler lasted a little over four days before it hit the 40°F. The RTIC comes equipped with tie-down slots, anti-slip rubber feet, rope handles with comfort grips, and T-handle latches. A nice perk of this cooler is that it has two drains, making it much easier and faster to drain. Unlike other T-handle latches in this roundup, we did not find the ones on the RTIC to be a pain to open.

Yeti Hopper Two 30

Cold hard facts: 23-can capacity; includes six tie-down points, three reinforced handles, a leak-proof zipper; three-year warranty.

Out of the many soft ice coolers that we tested, the Yeti Hopper Two 30 was the only cooler with a water- and leak-proof zipper. The Hydrolok zipper is durable and has a built-in seal in-between, making sure the cold air stays in for long periods of time. Although, due to the sturdy nature of the zipper, it is a little tough to open at times, but it’s definitely worth it for that good seal. It also has closed-cell foam insulation: a superior form of insulation compared to most soft coolers.

With its design of both zipper and insulation, this Yeti cooler was able to keep in ice for three days and 12 hours, impressive for a soft cooler. Besides its design on the inside, it has good added value features on the outside. All the handles are double-stitched which allows for easy carry for all loads. It has tie-down points on the sides, making it mountable. It also has multiple hitch points on the front and back of the cooler, allowing you to add any attachments you might want to bring along. Included also is a shoulder strap for easier carrying. Lastly, the bottom base is nice and flat, keeping the cooler upright at all times and adding that extra bit of sturdiness.

Yeti Tundra 45

Cold hard facts: 45-quart capacity, includes dry-goods basket and anchor point tie-down slots, five-year warranty.

During our testing, the Yeti Tundra 45 was able to last four days until the temperature reached 40°F. The T-handle latches are nice to use and aren’t too stiff. The drain works well, although it does not have a latch to stay onto the cooler. The rope handles are okay, the grips are sturdy and the length is a decent size. The non-slip feet work well and keep the cooler in place, as do the tie-down slots on the sides. The top of the lid is textured, which can be used for multiple purposes, including as a chair that won’t slide around. The included wire basket is a nice addition to hold any additional items that don’t need to be touching ice.

Everbilt 410-234

Cold hard facts: 52-quart capacity; includes built-in fish ruler, two cup holders, and bottle opener; UV-resistant; five-year warranty

Everbilt High Performance lived up to its name, keeping ice cool longer than any other in our roundup. It lasted almost six days before the internal temperature reached 40°F. The results impressed us even more because this cooler is half the price of many of its competitors. Besides the nice insulation, the Everbilt also comes plenty of crowd-pleasers like a fish ruler, cup holders, and a bottle opener.

When we finished the performance and portability tests, draining the Everbilt was a cinch. This cooler has a massive drain that has threads for a small hose. A chain keeps the drain cap from getting lost, a major plus when on the water or after a season of storage.

With excellent performance scores, we thought the Everbilt was going to claim a top spot. Then we did the portability testing. The Everbilt uses rope handles. Even though it has comfort grips, we found the ropes too long, making it extremely awkward to lug around. It does have pocket handles as an alternative, but it’s a tight squeeze for any adult hand. Also, speaking of being an adult, multiple grown men had trouble opening this cooler. While the T-handles provide a great seal, imagine waking up early in the morning—groggy and starving—to be bested by a cooler.

OtterBox Trooper LT 30

Cold hard facts: 30-quart capacity; includes a food-grade liner, waterproof external pockets, and bottle opener; limited lifetime warranty.

If there was ever an ice cooler, especially a soft-body cooler, to be described at heavy-duty, it would have to be the Otterbox Trooper LT 30. This massive ice “briefcase” is designed for short jaunts into rough terrain. In our tests, it was able to keep the temperature below 40°F for just over three days. The wide-mouth opening is an awesome design, making it easy to open and access.

It also has a great seal that is leakproof, so everything says inside. The handles are very durable and wide, making it easier to carry. As for wearing it as a backpack, it can be a bit awkward to walk around with, especially if it’s full of ice and beverages. However, the padded back and backpack straps help out a lot, making it more tolerable. The two front-facing pockets are a nice addition and it’s great that they too are waterproof. Also, on the front are two mounting brackets for accessories. Lastly, the base is very sturdy, keeping the ice cooler upright and protecting from abrasion.

Arctic Zone 16 Can Titan Deep Freeze Zipperless Cooler

Cold hard facts: 30-can capacity; includes a smart shelf, bottle opener, and zipperless open; limited lifetime warranty.

In our tests, the Arctic Zone Titan Freeze cooler lasted two days and 12 hours. The biggest feature to note is that this cooler doesn’t have a zipper to close the top of the lid. Instead, it’s just held by a Velcro strap, making it much easier to access and still have the ability to keep in the cold. Aside from having a lack of zippers, the Titan also offers some unique features such as the removable hard body liner and smart shelf, insulated pockets, and a bottle opener on the side. In addition to the large padded shoulder strap it comes with, it also has two handles on the side for any time you need to fully pack the cooler. The handles hide nicely inside two side pockets, which are also perfect for holding water bottles.

Igloo Marine Ultra 48 Qt Cooler

Cold hard facts: 48-quart capacity, includes two rules and UV inhibitors, one-year warranty.

In our tests, the Igloo Marine Ultra lasted three days and 12 hours before the temperature reached 40°F. For being a very simple ice cooler, there are some nice perks that go a long way, especially for those who want a cheap option for fishing. It has tie-down loops on the side so you can mount the cooler down. It also comes with two rulers on the top of the lid, one in Imperial and the other in metric.

The handles provide a comfortable grip and are currently our favorite out of all the box coolers that we’ve tested. They flip up to the perfect height and the comfort grips live up to their name. It does come with a drain hose, but there is no slope and the drain is higher than the base of the cooler, which can lead to sitting water unless you tip the cooler.

Igloo Island Breeze 48 Qt Cooler

Cold hard facts: 48-quart capacity, stain-resistant liner.

Even simpler than the Igloo Marine Ultra is the Igloo Island Breeze. Not offering too much, the Island Breeze is little more than a plastic box with some flip-up handles on the side. It doesn’t even come with a drain. In our tests, it was able to last a little over two days before the temperature reached 40°F. However, that’s over the advertised ice retention of one day. While this Igloo exceeded our expectations, it did not impress us.

Coleman 54-Can Collapsible Soft-Sided Cooler Bag

Cold hard facts: 50-can capacity, collapsible.

This Coleman cooler was able to keep in the cool temperature for just a little over 24 hours before the ice melted. It has two handles on the side with an adjustable shoulder strap. On the front, it has a decent-sized zipper pocket for holding items that don’t need to be cooled. Velcro straps festoon the exterior, keeping the lid closed, securing loops, and even allowing this Coleman to collapse into an easily storable mat. We should also point out that this Coleman was one of the few models that was not water-resistant.

Coleman 24-Hour 30 Can Cooler

Cold hard facts: 30-can capacity, includes a front pocket.

Similar to its 50-can counterpart, this Coleman cooler lasted a little over a day before it reached 40°F. It comes with two side handles and a shoulder strap. On the front, you’ll find a pocket that can fit slim items. While on the top, the biggest feature hides: A Velcro hatch, giving easy access to the cooler without having to keep opening the zipper.
