Backpack Cooler Reviews

YETI Hopper BackFlip Cooler Backpack at a Glance:

  • Capacity: 20 Cans (2:1 ice-to-can ratio)
  • Dimensions: 20.6 x 14.7 x 11.3 inches
  • Weight: 7.8 Pounds
  • Features: Mildew, puncture and UV-resistant exterior

With a price tag that could make your eyes water, the YETI Hopper BackFlip has a lot to prove and is our Editors Choice for the best backpack cooler.

So how does Yeti justify the cost?

As you would expect from YETI, they go the extra mile in terms of quality. Never satisfied with standard materials, the exterior features the Hopper’s high-density fabric, the dryhide shell.

Resistant to mildew, punctures and UV rays, it is tough, practical and stays waterproof even when dropped directly into water.

The top-quality materials extend to the shoulder straps, grab handle on top of the cooler and the two side handles if you want to share the weight.

On the inside, you’ll find an FDA-approved food-grade liner covering the Coldcell Insulation. This closed-cell rubber foam means the Hopper BackFlip can’t be flattened or folded, but offers superior cooling properties for a longer period of time when compared to products which are closer to backpack than ice chest.

The hydrolok zipper does it all. Waterproof, leak proof and as tough as old boots, it is the perfect zipper for a backpack ice chest as it prevents leakage even when on its side.

If you’re feeling flush and want the hardiest, coolest and most high-tech insulated backpack cooler on the market, the YETI Hopper BackFlip Cooler Backpack is it. Oh, and a three-year guarantee means even if anything does go wrong, you’re covered.

Coleman C003 Soft Backpack Cooler at a Glance:

  • Capacity: 28 Cans
  • Dimensions: 12 x 6.5 x 19.5 inches
  • Weight: 1.06 pounds
  • Features: Leak-proof heat-welded seams, BPA- and phthalate-free

The Coleman backpack cooler bag is a great choice if you need something practical that won’t slow you down. Weighing in at just 1.06 pounds, it is among the lightest of our choices with top features that make it a solid option.

The capacity and its stylish design combine well, especially if your main objective is to transport 28 cold beers to the beach.

The weight and style combination also makes it popular as a bag to take lunch to work in, and the BPA– and phthalate-free germ-resistant liner prevents mold, mildew and bad odors while at the same time being good for the environment and easy to clean.

For longer-distance treks, there is extra padding in the back and waist for comfort and adjustable shoulder and waist straps that can spread the weight out. The bag also features heat-welded seams which prevent leaks. This is an advantage for extended adventures in hot weather in which many bags leak melting ice.

The Coleman Soft Backpack Cooler has a lot of extra storage space. The main compartment is complemented by a zippered, insulated front pocket for smaller snacks and drinks, while the bungee cords on the front of the bag and the mesh side pockets can hold easy-access items such as water bottles and electronics.

While the Coleman C003 may not be quite at the level of the YETI Hopper BackFlip in terms of technology, its specification list is impressive. Its capacity, style and weight make it a serious contender for the best insulated backpack cooler.

Polar Bear Coolers Solar Bear Soft Cooler at a Glance:

  • Capacity: 18 Cans (with 7 pounds of ice)
  • Dimensions: 20.6 x 14.5 x 6.8 inches
  • Weight: 5 Pounds
  • Features: Keeps ice for 24 hours in 100+ degree heat

Polar Bear Coolers are very confident about their Solar Bear range.

Implementing their own technology at nearly every stage, they boast that the Solar Bear can keep ice for 24 hours in over 100 degree heat.

This is in part due to their one-inch thick 10 gauge high-density foam insulation. This combines with the durable interior liner which consists of antimicrobial tpu double-coated nylon.

On the outside there is a UV-resistant 840-denier outer shell and to guarantee no leakage, all of the seams are double hemmed and anchor stitched.

Similarly durable are the buckles and zippers. These heavy duty YKK components are super tough and super reliable, as you would expect from a backpack cooler bag of this price range.

The focus on durability does have an effect on the overall weight, 5.2 pounds, but most users see this as a more-than-worthwhile tradeoff.

Pockets on the exterior include a front zippered pocket which can be custom embroidered with a design of your choice. You can also find a pocket on one of the shoulder straps for all of your essential devices. And just as an additional extra, you’ll find a metal bottle opener attached to the zipper.

Like the YETI Hopper BackFlip, the Polar Bear Solar Bear Soft Cooler is tough, practical and keeps things cool for an impressive amount of time. At a fraction of the price and with a lifetime leakage guarantee, it also provides good value for money.

TOURIT Insulated Cooler Backpack at a Glance:

  • Capacity: 30 Cans
  • Dimensions: 13 x 7.5 x 15.8 inches
  • Weight: 1.1 Pounds
  • Features: Keeps cool for 16 hours when below 60 degrees with freeze packs

This versatile backpack lunch cooler works for all kinds of outside pursuits as well as for taking things to work.

Not as cumbersome as the most specialized insulated backpacks, but lightweight, with a good capacity and discreet look, TOURIT’s contribution is a great all-rounder.

It is well made, with a ventilated back to keep you cool and with a PEVA lining on the inside to help with leakage as well as maintaining temperature.

However, it is only one of two products on the list that claims to be leak resistant as opposed to leakproof.

The TOURIT insulated cooler backpack comes with a wealth of extra pockets for anything else you need to carry or access quickly. There are two front zipper pockets for small accessories, two side bottle holders and a mesh pocket on the strap.

This doesn’t mean the main compartment suffers though. With room for 30 cans, it holds its own against most other backpack coolers in this list.

In terms of coolness, it doesn’t really match up to the high-tech, high-price options. Keeping your snacks and drinks cool for 16 hours only when using freeze packs and when the outside temperature is under 60 degrees is far from best on this list.

But bear in mind that not everybody needs to keep things cold for much more time, and the pay off is that it is very light (1.1 pounds) and can be folded nicely for storage.

This is a great backpack for those of you that are happy to live without the best possible quality.

Compared to others, it could be seen to not hold its temperature or its water well enough, but considering its price, anybody who is not a hardcore adventurer would most likely be more than happy with the TOURIT Insulated Cooler Backpack.

OAGear Ultimate Backpack Cooler at a Glance:

  • Capacity: 20 Cans (plus ice)
  • Dimensions: 12 x 10 x 14 inches
  • Weight: 1.5 Pounds
  • Features: Leak-proof double heat sealed PEVA liner

Toward the lower end of the price range, the OAGear Ultimate Backpack Cooler provides a lot of chill for your buck.

It is a stylish backpack ice chest which won’t look out of place whether you’re taking lunch to work, chilling out on the beach or going for a walk in the woods.

At just 1.5 pounds, it is light and easy to carry.

Despite the lower price, the OAGear Ultimate Backpack Cooler has an impressive capacity, with room for 20 cans plus ice.

It is a very practical bag, with two zippered side pockets that can easily hold any kind of phone, sunglasses or some smaller snacks. A large front slip pocket can is for all kinds of other gadgets, even up to the size of a tablet.

The guys at OAGear don’t skimp on quality, with a double-heat-sealed PEVA no-leak liner preventing any melted ice dripping through. The exterior is made up of 600 denier polyester with 600 denier ripstop trim.

The OAGear Ultimate Backpack Cooler is among the best cooler backpacks for the money options on our list. It is suitable for most normal activities, such as trips to the beach or family hikes.

Only when you start getting really serious should you consider splashing the cash on something more specialized.

ROCKBROS Waterproof Backpack Cooler at a Glance:

  • Capacity: 36 Cans
  • Dimensions: 14.8″ x 11″ x 20″
  • Weight: 4.2 Pounds
  • Features: Airtight zippers, leak-resistant, antimicrobial liner

Similar to the YETI Hopper Backflip above, the ROCKBROS Waterproof Backpack Cooler, is a inexpensive alternative with performance that is very close.

The ROCKBROS is a rugged cooler made with a 840D Nylon + TPU shell that is 100% waterproof and with an airtight zipper, leakproof and maximizes chill time by keeping warm air out.

What good is a backpack cooler if it’s uncomfortable to carry? The ROCKBROS features a foam lined backing along with padded shoulder straps for all day comfort.

It has a leak-resistant, antimicrobial liner which works well to resist smells and is easy to clean.

Its forte is its practicality. The bands on the side allow to carry items like a water bottle or keys. With a 36 can capacity or 20L, it can be loaded with up to 40 pounds of food and beverage.

If you are looking for a solid YETI alternative with solid specs and excellent performance at a bargain price the ROCKBROS Waterproof Backpack Cooler is a perfect option for a day at the beach or camping trip.

MIER Insulated Cooler Backpack at a Glance:

  • Capacity: 24 Cans
  • Dimensions: 11 x 7.9 x 13.8 inches
  • Weight: 1.4 Pounds
  • Features: Good value for money, Leak-proof heat sealing

Again for those who want value for money, the MIER Insulated Cooler Backpack offers excellent quality at a very low price. Its discreet, sporty look is great for family days out to theme parks or just a day trip.

The thick insulation works in combination with the leak-proof PEVA liner to keep everything in your ice chest fresh. The vast interior holds 24 cans, or easily enough food for four people for a day.

Aside from the large interior, it is full of other practical pockets. The inner mesh pocket on the lid is great for storing small items that need to be kept cool, while the two side mesh pockets are easy-access spaces for things like water bottles.

The larger of the front zipper pockets has a mesh divider for utensils, while the smaller one provides storage for anything you haven’t already found a home for.

The padded grab handle on the top lets you pick it up easily when you’re moving it a short distance

As one of the low-cost choices on this list, the MIER Insulated Cooler Backpack cannot offer the latest in ice chest technology, but is still a solid option. This stylish, spacious and practical bag is ideal for moderate hikes or fun days out.

How to Choose the Best Backpack with Cooler

best cooler backpack

Although at first the amount of insulated backpack coolers can seem overwhelming, once you identify exactly what you need, the choice becomes far easier.

Considerations for Backpack Coolers

The following questions should help you to decide which backpack cooler is right for you.

What do you need it for?

All of the backpacks listed here are top-quality products, but choosing just one really depends on what you want to use it for.

When time and heat are a concern, then you should start looking at the more specialized models. Fishing, hunting and hiking are all the kinds of activities which should make you consider going for a model which is closer to a traditional ice chest in terms of cool time and durability.

A backpack lunch cooler for family hikes should focus on comfort and weight, while maximum capacity is not quite as important. Walkers can also benefit from extra pocket spaces which come in handy when you have a lot of gadgets you need to carry around.

How long do you need the ice to last?

As impressive as the high-tech models in this list are, if you just want a bag to take to the beach, spending big is probably not worth the money.

However, if you’ll be hiking through the wilderness for hours on end, perhaps on a fishing trip or a trekking holiday, one of the sturdier options, which stays cooler for longer and has a tougher exterior, is what you need.

Many users need an all-rounder which works just as well by the sea, on the trail and in the office. These bags are usually at the lower end of the price range, but are high on practicality, with extra pockets, a sleek design and can possibly be folded.

What will you be storing in it?

Let’s not kid ourselves; there are some of you reading this who know that you only need a beer cooler backpack to keep those precious cans cold all day long while you’re lying on the beach. In that case, weight and comfort won’t be too much of a concern, whereas capacity and how long it stays cool will be top priority.

For taking your lunch to work on a daily basis, there is no need to go for the top-spec models. One of the lighter, more discreet models will work perfectly well.

Will you be wearing it for extended periods?

For beach trips where your cooler will be going from the car to the sand and back again, you won’t need to focus much on the comfort side of things.

However, all outdoorsy people will know that carrying a lot of weight on your back all day long isn’t fun, so hikers and people who will use the bag on a daily basis should take weight and comfort into consideration.

Chill Time

The technology used to keep your gear cool improves year on year, and as with most things, you get what you pay for.

Industry-standard foam does the job, but the specialist insulation from YETI and Polar Bear are on another level, capable of keeping their cool for up to 24 hours.

Cooler Insulation Types

This kind of goes hand-in-hand with our last point about chill time. but insulation obviously plays a huge role in how your cooler performs. As far as insulation types, you will find find two main types: polystyrene and foam.


The most common and least expensive type of coolers will use insulation that onsists of a foam lining. A foam lining works well if you just need to chill items for a few hours, or for less than a day, as it isn’t as effective at keeping ice as polystyrene. However with enough thickness it can be effective for longer periods of time.


This is the best insulator for a backpack cooler that you can get. It’s a type of plastic, which means it’s cheap, relatively lightweight, is poor at transferring heat, and is very durable. As a rule of thumb, the thicker the walls of polystyrene are, the better it’s going to insulate the items inside.


Size always matters when choosing a backpack with cooler.

Most people would naturally lean toward the larger bag, but don’t forget to keep in mind that they can be more difficult to store and the bigger they are, the heavier they are.


Both inside and out, all of these backpack coolers are tough. However, there is still a vast difference between the most expensive and the least.

Regarding the exterior, high-density materials are more resistant to tears, while ripstop fabrics can keep your straps and handles in tact even when subjected to considerable weight.

One key problem with some cheaper beer cooler backpacks are that as soon as the ice inside melts, the back of your legs know about it. However, all of the products you can find in this article are at least leak resistant due to their superior build quality.

Again, leakage won’t be a problem if you only need your bag for a few hours, but anything more than that and you should really start looking at the pricier options.

One way of reducing the effect of leakage is to buy ice packs. They don’t turn to water like ice cubes do and in the long run, the fact that they are reusable means they work out cheaper than buying bags of ice.


A backpack’s durability and cold retention capabilities have an effect on the weight. The more effective the insulation, the heavier it will be.

Items in this list vary in weight by about 4 pounds, so if you’re going to be on the move a lot, try looking for the lighter options.


Some of the less expensive cooler backpacks on this list have the serious advantage of being lightweight and having a range of pockets to use.

This is especially beneficial for users who use their backpack on a day-to-day basis. The advantage is that it is closer to being a backpack which is also a cooler, rather than a cool box on your back.

FAQs About Backpack Coolers

Q: Do I need to lubricate waterproof zippers?

A: Most waterproof zippers come pre-lubricated and may not need to be lubricated again. However, if the zipper starts to pull and tug where before it moved smoothly, then it might be time to lubricate with beeswax or other alternative.

Q: Can a soft cooler backpack be flattened for travel?

A: The answer is, yes and no. If the soft-sided cooler doesn’t have a hard inner liner, it can usually be flattened to place it in a backpack, or to be packed more easily in the vehicle for transport. Those soft-sided coolers that have a hard liner can’t be flatted, but that is part of what makes them effective for insulation.

Q: Will a backpack cooler work for both hot and cold items?

A: Many backpack coolers can be used to keep both cold items cold and hot items hot. Not all of them have this feature however. So be sure to check the manufacturer specs before using for hot foods.

Q: What does “BPA Free” mean?

A: BPA or bisphenol A has long been used in plastics that are used in conjunction with food. These chemicals, when in large amounts, may be unhealthy. By choosing not only soft-sided coolers but also food containers and other plastic products that are BPA free, you are ensuring that no harmful BPA chemicals are near your food and drink.
