What Is The Best Backpack Cooler? 

 June 19, 2023

Backpack coolers are a convenient way to keep your drinks cold for hours while you travel. There are many different kinds out there, but what should be taken into consideration before buying one?

There are a few factors to consider before buying a backpack cooler. Choose its capacity based on the number of people in your group and your chosen activity. It should have a decent insulation time, be waterproof, be made of quality fabrics, and be comfortable to wear. 

Aside from these, there are other things you should think about before deciding on a backpack cooler. Read on below to learn more.

Features Of The Best Backpack Coolers

Backpack coolers are a travel essential: they keep your food and drinks cool for several hours while keeping your hands free. Whether it’s for a day trip, picnic at the park, camping, or just about any trip in the outdoors with your family and friends, backpack coolers are the perfect way to transport your beverages. 

Because they are so convenient for traveling, it’s no surprise that backpack coolers have become so popular. They are now something essential for anyone who spends lots of time outside of the home. Additionally, they are an excellent alternative to traditional hand-held hard-side coolers, which can be uncomfortable and heavy to carry around.

Backpack coolers come in a wide range of styles, shapes, sizes, and features. Before you decide on a backpack cooler, think about these:


How and where do you intend to use your backpack cooler? How many people are you packing drinks for? Are you going to a place with hot temperatures or one that’s cool?

The answer to these questions should influence the capacity you choose, as well as its insulation and design. Some backpack coolers are waterproof and compact enough to be strapped onto a stand-up paddleboard, while others are bulkier and designed to keep drinks cool for a large group of people. There are also some models that are designed to help you carry other items other than just snacks and drinks so that it’s more convenient for you to travel.

You may need significantly more features and waterproofing ability if you are going to use the cooler pack on a boat or fishing excursion, though simple features will do for picnics, a trail hike, or a backyard bbq. 


Cooler backpacks range in capacity from 10 liters to as much as 65 liters. Small and compact coolers can accommodate drinks for 2 people, while larger coolers can store beverages for a big group going to the beach for the weekend. Most cooler backpacks are between 20 to 30L, which is enough space for a few bottles of wine, plus cheese and fruit for around 4 to 5 people. 

Choose the size and capacity of the backpack cooler carefully. You shouldn’t opt for a 40L cooler if you plan to go hiking in the backcountry, because it can weigh as much as 60 pounds once it’s loaded with drinks and food. It may have lots of room, but in reality, they are far too heavy to carry. 

If you need to keep drinks for up to 3 people for a few hours, such as a football game or picnic, choose a backpack cooler that’s around 20 liters. On the other hand, if you are going on a weekend or road trip, opt for a 30-40 liter backpack, which is suitable for keeping enough drinks for you and your friends. 

When shopping around for backpack coolers based on capacity, you may find that how many cans a cooler can hold might be a more useful metric. Small coolers can hold around 6 cans plus ice, while larger coolers can accommodate as many as 25 beer cans or soda with ice. Knowing how and when you’ll be using the backpack cooler will ensure you always have ample space for everything. 

Insulation and Cooling

Backpack coolers have varying ice retention capabilities. Some models are better equipped to stay cool for 24 hours, while some are only able to keep the contents cold for 12 hours. Higher-end models made of premium insulating materials will be able to stay cold for much longer.

Generally speaking, it’s standard for most coolers to offer ice retention for 24 hours. However, remember that there are many other factors that will affect insulation even if you invest in a pricey backpack cooler. How often you open the lid, temperature, and the sunlight the cooler is exposed to will all impact how long the cooler's contents stay cool.  

To increase the insulation capabilities of your cooler, you can fill it up with ice packs a few hours before you head out on the road. This will effectively reduce the interior temperature and help it stay colder for longer. 

Check out the manufacturer’s claimed ice retention before buying; most brands provide this information to let customers know how long it can stay cool, on average. 


Different kinds of soft, pliable fabrics are used to manufacture cooler bags. Interiors are usually made with open-cell foam or closed-cell polyurethane foam, though the latter is typically used in higher-end models because of its superior cooling abilities.

However, if you intend to store food such as produce and vegetables, it would be wise to choose interior linings that are also food-safe.

When it comes to exteriors, choose a cooler pack made with durable polyester fabrics that are at least tear and rip-resistant. A cooler with waterproof material is recommended if you intend to bring it with you on the beach or boating excursions. Avoid backpack coolers made with canvas or other fabrics that are not water-resistant because they are prone to leaking melted ice.

Keep in mind that the type and quality of materials used in backpack coolers (insulation, exterior, interior liner, back panel, shoulder straps, etc) will have a great influence on how waterproof it is. The fabrics will also play a role in its insulation, breathability, comfort, and durability. 

As with other backpacks, premium fabrics will cost more. However, high-end fabrics will also last you a much longer time, especially in the outdoors, where regular exposure to the elements can damage a backpack more quickly. 


Backpack coolers come in a variety of designs: some are softer and more comfortable, while others are more rigid and tough.

Check for the bag’s denier rating, which tells you how thick and durable the fabric is. Coolers with more solid construction and shape will usually have a higher denier rating (around 800-1000D); these are better suited for rugged outdoor use. 

Softer backpacks are more comfortable to wear. They may break easily but are recommended for casual, occasional outdoor use. 


Without quality waterproof materials and construction, a backpack cooler can be prone to spills, risking the safety of the rest of your gear. The exterior fabrics and interior liners should be waterproof to prevent this; also look out for welded seams and a waterproof lid zipper. If the exterior fabric produces condensation due to its contents, you may also have to deal with puddles later on.

Some people may also appreciate water-tight and airtight backpack coolers. Water-resistant zippers are excellent for this, as well as preventing leaks. Some coolers are made with dry-bag materials, which even allow you to submerge them in water. 

A waterproof model is perfect for paddleboarding, boating, kayaking, fishing, and other water sports. 


Backpack coolers make traveling or hiking with cold drinks so much easier.

That said, they aren’t meant to be carried for long periods of time. They are not like backpacking backpacks that you can trek distances with because the nature of their contents is simply far too heavy for one person to haul for several hours at a time. 

Most people can carry backpack coolers for under an hour. Perhaps you just need to transport drinks from a vehicle to a campsite, a tailgating party, short day hikes, or a nearby beach. 

Regardless of where you are going, always go for backpack coolers that have adjustable, wide, padded straps for added comfort. Padded shoulder straps are non-negotiable; otherwise, thin straps may dig into your shoulders and be uncomfortable to carry. 

Some backpack coolers are equipped with padded back panels for more support and comfort. Some models have hip straps to distribute the weight to your hips – this is an extremely handy feature for those who will be walking long distances. 


Backpack cooler prices range from $25 to as much as $700. There are many things that affect the price, such as the brand, insulation, size, and materials used.

The most popular backpack cooler models have an average price of around $50, which is fair if you are buying from a reputable brand that is known for durability. You’ll be able to score a great deal if a brand goes on sale too. 

Optional Features To Consider

Check out these additional features to consider before buying a backpack cooler:


Pockets and compartments allow you to keep your valuables, not just perishables, in your backpack cooler. For example, you might find it handy to have a small zip compartment on the cooler exterior as storage for your keys, phone, or wallet. Side pockets are beneficial for keeping other valuables, such as your utensils or water bottles, in easy reach.

These are extremely helpful, especially if you don’t plan on bringing another bag for a day at the beach. Bonus points if the pockets are waterproof too. It will give you a bit more assurance that your essentials stay dry even when there is some precipitation from the cooler’s contents. 

Top Handles

Being able to switch from backpack to a hand-carried cooler is a convenient option for some travelers. The top handle will allow you to grab the cooler by your hands and transport it a short distance, in case your back starts hurting or you want to give your shoulders a break.

Beer opener

A beer opener is a useful extra feature that is found in many cooler products. If you frequently tend to forget to bring a beer bottle opener, this will come in handy. Few things can be more disappointing than setting out to relax in your campsite after hours of driving, only to realize you left a beer opener behind. 

Durable & Easy Clean Bottoms

The bottom of a backpack cooler will be exposed to sand, soil, dirt, rocks, and other terrain. That said, it’s going to get dirtier much quicker than the rest of the pack. 

Backpack coolers with reinforced bottoms, and those that are easy to clean with a quick wipe, will save you loads of cleaning time. More durable bottoms will also last longer.
