The large front pocket provides extra storage space for accessories, and the molle straps feature a convenient bottle opener.


Corkcicle Eola Bucket Bag

Most Comfortable: Hydroflask Day Escape


The Hydroflask Day Escape is the most comfortable backpack cooler.

Key Features

However, it lacks a hip belt, so it's recommended not to overload it for more extended hikes. It also features a convenient haul handle, not commonly found in backpack coolers, for easy storage at home.

Laura Lancaster Apart from its comfort, the Hydroflask Day Escape excels as a backpack cooler. It is fully waterproof and keeps ice intact for up to forty-eight hours in insulation testing.

Most Versatile: RTIC Soft Pack


The RTIC Soft Pack is the most versatile backpack cooler.

Best Insulation: Icemule Jaunt


The Icemule Jaunt has the best insulation of all the best backpack coolers.

Key Features

  • Capacity: 9 liters
  • Weight: 1.5 pounds
  • Insulation Test: 72 hours


  • The Icemule Jaunt is an affordable option with a lightweight design.
  • It features a roll-top for space-efficient storage, a zip pocket at the front, and exceptional insulation.


  • No padding at the back panel.
  • Not fully waterproof.

For hikes in hotter climates, the Icemule Jaunt serves as the perfect backpack cooler to keep your lunch and snacks at an optimal temperature. While it may not be visually striking, it offers impressive ice retention, lasting up to 72 hours in testing. Despite its compact size, it has sufficient space for drinks and food for two individuals. The inflatable insulation, roll-top closure, and lack of rigid structure allow for easy packing and storage.

While the straps on the Icemule Jaunt is padded, there is no padding or shaping along its back panel.While the straps on the Icemule Jaunt are padded, there is no padding or shaping along its back panel. Laura Lancaster However, the Icemule Jaunt could benefit from additional storage pockets on the sides to accommodate other hiking essentials. Due to its lack of internal structure and back panel padding, extra care is required during packing to avoid objects poking into the back. The roll-top closure, while efficient for space-saving, doesn't provide the same level of waterproofness as zippered models, as it may leak when inverted for more than a few seconds.


Best Value: Icemule Pro Large


The Icemule Pro Large is the best value.

Key Features

  • Capacity: 23 liters
  • Weight: 3.2 pounds
  • Insulation Test: 48 hours


  • The Icemule Pro Large offers generous capacity at an affordable price.
  • It features a padded back panel and a roll-top closure.


  • Less comfortable for carrying compared to other models.

While the Icemule Boss receives much recognition for its day pack-like appearance, the Icemule Pro Large shouldn't be overlooked as it provides significant insulation at a fraction of the price. It maintains ice for 48 hours, making it suitable for weekend camping or boating trips. Although not entirely waterproof, proper care should be taken to keep the cooler upright, especially when ice begins to melt.

A valve on the Icemule Pro can be used to inflate the insulation chambers for some added oomph, and then deflate again for storage.A valve on the Icemule Pro can be used to inflate the insulation chambers for some added oomph, and then deflate again for storage. Laura Lancaster While it lacks a substantial hip belt for carrying larger, heavier loads that the Pro's capacity allows, it does feature a padded back panel that helps alleviate the load over shorter distances. Despite its seemingly oversized appearance, the Icemule Pro can be easily packed down, thanks to the roll-top closure and deflatable insulation.


What To Consider When Buying A Backpack Cooler



Ice Retention


Consider how long you need to keep food and drinks cold when selecting a backpack cooler. High-end brands like Yeti and IceMule offer longer ice retention, but they come at a higher price. On the other hand, more affordable brands like Igloo and Arctic Zone may not retain ice for as long. It is important to evaluate whether you need extended ice retention or shorter cooling periods.


Strap System


If you plan on carrying your backpack cooler for an extended period, it is crucial to choose one with supportive and comfortable padding. Look for models with hip or chest belts to distribute the weight and reduce strain on your shoulders. However, if you only anticipate short walks from your car, a hip belt or padded straps may not be necessary.




Backpack coolers come in different sizes, so it is essential to consider your capacity needs before making a purchase. Determine the amount of food and drinks you plan to carry, keeping in mind that ice cubes occupy a significant portion of space within the cooler.




Decide whether you require additional features like pockets and dry storage compartments. Pockets can be useful for storing personal items such as phones, wallets, keys, and water bottles. If your backpack cooler will be your sole carrying item, having pockets for organization can be convenient.




Backpack coolers are available in two main types: boxy and stiff coolers, and flexible soft-sided coolers. Boxy coolers have a flat bottom, making it easier to load and store food and drinks. However, they can be less comfortable to carry. Soft-sided coolers, like the Hydro Flask Day Escape and REI Cool Trail Pack, are more comfortable to wear as backpacks, but they may be slightly less convenient to load cans into.


How To Pack A Backpack Cooler Like A Pro


Kieran Kreevy, an International Mountain Leader and backcountry chef, shares tips on preparing your backpack cooler and its contents for a superior outdoor experience.

To maximize cooling efficiency, use ice blocks and ice packs as your main sources of cold. Fill any empty space with ice cubes. It's important to pack your backpack cooler as full as possible to prolong its cooling performance. If there is enough space, pre-cooling the backpack cooler in the fridge or freezer can be beneficial.

Ensure that all items you plan to put in the cooler are properly chilled. Keep in mind that even in freezing conditions, food left in direct sunlight can spoil quickly. If you're bringing meat, opt for fish or beef instead of chicken or pork as they are less prone to spoilage. Pre-cutting raw chicken and freezing it before transport can help prevent contamination.

Insulated containers can provide extra assurance that ingredients won't get warm. They are especially useful for carrying temperature-sensitive items like ice cream. Preparing food in advance can also save cooking time and reduce the amount of waste you need to carry. However, remember to properly dispose of items that do not decompose quickly, such as banana peels.

Loading your backpack cooler properly is crucial, especially when carrying delicate ingredients like leafy greens and fresh berries. Keep these items separate from ice and cool blocks to prevent freezing. Additionally, grouping cold goods separately (drinks, snacks, meal ingredients) helps maintain the cooler's temperature and reduces the need to search through an open cooler, which can let cold air escape.


How Long Should Ice Last In A Cooler Backpack?


The duration of ice retention in a backpack cooler depends on factors such as the cooler's insulation, outside temperature, and frequency of opening. Ice can last anywhere from 12 hours to 7 days. High-quality hard coolers generally offer the longest ice retention, while soft coolers may only maintain ice for a day in warm conditions.


In conclusion, when it comes to choosing the best backpack cooler for your hiking adventures, there are plenty of options to consider. From the spacious storage capacity and additional features of the Camelbak Chillbak 30 to the durability and insulation of the RTIC Backpack Cooler, each cooler offers its own unique advantages. Whether you prefer the sleek design of the Hydro Flask 20L Day Escape or the versatility of the IceMule Classic Medium, there is a backpack cooler out there to suit your needs. So pack your cooler like a pro, keep your beverages ice cold, and embark on your hiking journey with confidence, knowing that you've got the best backpack cooler by your side.
