Finest Small Coolers of 2023

There are plenty of trips for which your heavy-duty camping cooler is overkill, and investing in a small cooler can help save precious cargo space in your car. But your needs for an all-day outing to the beach compared to a weekend-warrior style overnight stay at a dispersed campsite can vary considerably. After checking out ten of the most popular models from the best known brands, and scoring them on a number of criteria, I’ve settled on the best small coolers for a range of activities. 

How I Tested the Best Small Coolers

The basis for my test of the top small coolers was ice retention. To ensure as level a playing field as possible, I put one bag of store-bought ice into each of the ten coolers at the same time and then kept them in the same room. Whenever I checked the ice in one cooler to see if it had melted, I checked it in all of them. Next, I checked how watertight each cooler was, including at the drainage port (where applicable) and around the lid, by filling the cooler with water and then tipping it in a variety of directions. I also screwed and unscrewed the drainage ports multiple times to get a feel for how waterproof (or lack thereof) each was—unloading your car only to find a puddle forming underneath your tent or sleeping bags is not an experience anyone wants to have. Finally, I looked at how difficult each latching system was to operate. 

I also considered the accessories provided with each cooler, how easy it was to transport or move, and the overall cost. Recommendations also took into account the size of each cooler, how easy they were to open and close, and whether they collapsed down after use (to better fit into a small or midsize car).

The Best Small Coolers: Reviews & Recommendations

Best Overall: Kula 2.5

Key Features

• Capacity: 9.5 liters (also available in a 22 liter size)
• Weight: 3.5 pounds
• Hours for a bag of ice to melt: 61

Pros

• Best-in-class ice retention
• Water resistant 
• Can double as a beverage dispenser

Cons

• Expensive
• Not as comfortable to carry as others I tested

I wasn’t expecting the best small cooler test to be a bucket, but the Kula 2.5 performed so well during the ice retention, waterproofness, and usability tests that it couldn’t have been any other way. It took over 2.5 days for a bag of ice to melt in this cooler in hot, muggy conditions (70 to 80 degrees with an average of 50 percent humidity). And while other coolers that made it into day three of the ice retention test were starting to irk me with their difficult-to-use latches, the rubber toggle on the Kula was a breeze to move up and down. Its cylindrical shape made it a bit of a chore to cart around, so if you’re planning to hike in a distance before using your cooler it might be better to go with the most portable pick on this list.

In addition to a bottle opener, the Kula 2.5 also incorporated two drainage options: a classic port located unusually on the underside of the cooler and a spigot on the body, allowing this small cooler to also double as a beverage dispenser (Don’t worry; it’s made from food-grade plastic). 

Best Lightweight: Oyster Tempo

Key Features

• Capacity: 24 quarts 
• Dimensions: 20.1 x 11.8 x 12.6 inches (exterior)
• Weight: 12.3 pounds
• Not IGBC-certified

Pros

• Very lightweight
• Space efficient

Cons

The Oyster Tempo is an impressive cooler. It maximizes interior storage better than anything I’ve tested. It’s also astonishingly lightweight: even completely full, I was able to carry it on one shoulder using the supplied shoulder strap. But it also has some serious weaknesses, especially for individuals accustomed to using more traditional coolers.

Let’s start with how the Oyster got so light in the first place. Most coolers use polyurethane insulation in between the interior and exterior plastic walls, but the Oyster has nothing inside its walls, not even air. This vacuum seal goes a long way toward preventing heat transfer from one side to the other (it’s also how the best camping mugs and best thermoses are designed). Further, rather than being made from a plastic so heavy duty that you can drop it off a cliff and be no worse for wear, the Oyster is made from a comparatively thin aluminum. For the vacuum seal of the Tempo to be effective, Oyster also eliminated the drainage holes. That means that if you choose to chill your drinks or food with ice, draining the water out will be pretty difficult. For that reason, Oyster recommends using one of the best ice packs for coolers. 

I tested this cooler over a number of camping trips and came away both impressed and disappointed. I loved how small it was, it took up half the space as the Stanley Adventure I had been using previously, and effectively held just as much. It was also very easy to move around, which was helpful on trips when we moved campsites frequently. Finally, the vacuum sealing does work at scale: It did a surprisingly good job at keeping things cool. Filling about half the cooler with ice packs was sufficient to keep everything chilled for up to four days, even at the peak of summer. On trips that were longer than that, we would have to get creative about how to keep things chilled, either purchasing frozen items to stack in next to the milk and vegetables, or dealing with the hassle of melting ice without a drainage hole. 

The biggest issues with this cooler are the lid design and how comparatively fragile the vacuum sealed aluminum is. While switching out the ice packs in a parking lot at one pit stop, I picked up the cooler by the lid in order to turn it upside down and let the excess moisture from the coolers’ contents run out. While this is something that most of us have done with other camping coolers over the years, you really should not do this with the Oyster Tempo. On this cooler, the lid opens on both sides, and is held shut by a relatively simple clasp. Holding it by the lid caused the clasp to pop open, and the cooler fell a few feet to the ground. Even empty, this was enough force to dent the bottom of the aluminum shell. While this did not damage the vacuum seal (we used the cooler for the rest of our trip without incident), it was fairly unsightly and spoke to the overall fragility of the cooler. Don’t throw this one off a cliff, or at all. 

Here’s the thing, though: even with the issues I had with the lid mechanism and damaging the cooler, I still reached for it again and again throughout the summer. It’s lightweight, spacious design more than makes up for these faults. If you’ve been frustrated by the cumbersome builds of more traditional coolers and are looking to try something new, then this should go to the top of your list. 

Key Features

• Capacity: 19 liters
• Weight: 17.6 pounds
• Hours for a bag of ice to melt: 56

Pros

• Excellent ice retention
• Easy to use latch

Cons

The Dometic Patrol 20 looks as if someone took a regular-sized cooler and then shrunk it down until it was child-sized. There are some negatives to this—mainly that it’s pretty beefy, and thus heavy and awkward to carry even when completely empty. But the positives easily outweigh this con. Not only was the Dometic Patrol 20 one of the top performers for ice retention in my test, lasting well over 48 hours in the August heat, but it also had some of the easiest-to-use latches in my test. If you’re looking for something smaller than a traditionally sized cooler to pack up your perishables for a long weekend camping then this is a smart choice. 

Key Features

• Capacity: 19 liters
• Weight: 6.5 pounds
• Hours for a bag of ice to melt: 45

Pros

• Best ice retention of a soft-sided cooler in my test
• Excellent waterproofness
• One of the more comfortable small coolers to carry in my test

Cons

• Latch is somewhat fiddly to use
• Expensive

The OtterBox Trooper 20 is a soft-sided cooler that shares some important similarities with the hard-sided coolers in my test. First off was the lid, which is made from a heavy-duty plastic that gave the overall structure of the cooler more support than other models I tested (although, don’t be fooled by the soft foam on top—sitting on this cooler will cause it to collapse). It also had excellent ice retention capabilities, performing well beyond the other soft-sided coolers I tested and coming in within a few hours of some of the traditional hard-sided coolers I looked at. 

Something I didn’t like about the Trooper 20 was its hard plastic latch. It was easily the most complicated to use in my test, with the latch tending to slip down the hook rather than go cleanly over the top. It also squeaks quite loudly, suggesting that more tension is being placed on the plastic than it is designed for. Fortunately, this was one of the few coolers I looked at that had a limited warranty in the event the latch breaks.

Other features that are unique to the Trooper 20 included a waterproof front pouch that’s large enough to store a couple of phones, battery packs, and a bottle opener. I also liked how the balance of this cooler, which is flat on one side and curved out on the other, made it less awkward to carry than the more classic rectangle design. 

Key Features

• Capacity: 20 liters
• Weight: 3 pounds
• Hours for a bag of ice to melt: 37

Pros

• Very comfortable to carry
• Waterproof

Cons

• Narrow design makes it more difficult to access the bottom of the cooler
• Backpack straps are difficult to adjust

If you’re planning to travel more than a 100 yards with your cooler, you’ll start to notice all the ways in which they are awkward to carry: sharp corners, abrasive fabrics, unbalanced loads. Backpack coolers help to mitigate these issues by adding on the strap and support structure typically used on packs for day hikes. So it was no surprise that the Hydro Flask Day Escape was the easiest to carry of any small cooler I looked at, although there are a few things that I wish had been different about its design. The straps themselves were exceptionally hard to adjust, requiring some serious yanking to get them to move at all (forget about dialing in a precise fit). The sternum strap was also located unusually high up—at its highest point, it was just below my neck and it only came down a couple of inches below that. But the light padding on the pack and straps helped to make up for the awkward parts of this backpack cooler, earning it top marks in comfort. 

I also liked that the Hydro Flask Day Escape was fully waterproof, tipping easily in all directions without letting any moisture escape. Although if you work up a sweat on your day hike it’s never a bad idea to pour some of the runoff over your head.  

Key Features

• Capacity: 21 liters
• Weight: 4 pounds
• Hours for a bag of ice to melt: 38

Pros

• Good ice retention (for a soft-sided cooler)
• Waterproof
• Comparatively low price

Cons

• Zipper is tough to open and close
• Boxy shape makes it less comfortable to carry than others in my test

This soft-sided cooler from RTIC checks all the boxes: waterproof, holds ice for over 36 hours, good-looking design, and reasonably priced, less than half the cost of some of the other high-end models I tested. As a bonus, it even had a waterproof pouch on one side that fit my phone (although not much else). 

While the overall design of this soft cooler is aesthetically pleasing, it was a bit of a chore to cart around. The boxy shape tends to bang around against your thighs, whether you are using the haul handles or the shoulder strap. And though I appreciated how watertight the zipper of the RTIC Soft Pack 30 was, it was one of the toughest to open in my test. That being said, if you plan to use your soft cooler primarily on a boat or other stationary location, and only plan to open it a handful of times, then this is an excellent value.

Things to Consider Before Buying a Small Cooler

Purpose

What small cooler is right for you depends largely on what you plan to do with it. Those looking for an easy grab-and-go option to store beverages or the best camping snacks will likely prefer the larger capacity of soft coolers while individuals that need to keep the brats chilled for an overnight camping trip should go with the better ice retention of a hard-sided cooler.

Waterproof vs. Water-resistant

One of the biggest differentiators between the soft coolers in my test was their level of waterproofness. The RovR TravelR 30, RTIC Soft Pack 30, and Hydroflask Day Escape were all fully waterproof. No water escaped from the seams during the ice retention test, and no water leaked out the top or around the zipper when the cooler was flipped around while filled with water. As long as these three are fully zipped, you won’t need to worry about a cooler full of melted ice water tipping over in the back of your car. Of the hard-sided coolers, only the ORCA 20 Quart was fully waterproof. 

Latching Mechanism

Latching mechanisms need to thread a fine needle: be sufficiently airtight and watertight to prevent cold air or moisture from escaping out the seams while also being easy enough to use that you can trust friends and family (including children) to actually use it. A latch that is too difficult to pull or snap shut will inevitably be left open, reducing the overall efficiency of the cooler. In the above table, I’ve rated the functionality of each latching system to help you evaluate which cooler is right for your purposes.
