Today’s modern backpack coolers for the outdoors
solve a fundamental problem campers, hikers, and fishermen and women have struggled with for years: keeping your drinks and food cool without carrying a bulky, hard-sided cooler for miles into the wilderness. Old school coolers just aren’t great for lengthy hikes. Plastic coolers are cumbersome, heavy, and awkward to carry for long distances. Fortunately, today’s cooler backpacks have better insulation and can even retain ice longer.
Before you buy something for your next backcountry camping trip or a day of fly fishing, check our picks for the best backpack coolers that will make your outdoor adventures a lot more enjoyable.

Pros
Superior ice retention
Comfortable and lightweight to carry
Large capacity

More expensive than others we tested
Yeti is the gold standard of coolers, and the Hopper M20 is no exception. I’ve been using the Hopper for years now as my go-to backpack cooler, whether I’m going camping, heading out on the boat, or just spending an afternoon at the beach or pool. It’s big enough to hold drinks for an overnight trip yet small enough that it doesn’t feel overkill for a day outing.

What really sets the Hopper—and any Yeti cooler
for that matter—apart from the others is its ice retention. Thanks to the unique closed-cell foam insulation, it can keep ice frozen for at least 24 hours. I can personally attest to this. I left it outside in the summer with ice inside overnight and woke up to still-cold drinks.

Other highlights are the leakproof liner, double-stitched construction for durability, and exterior grid design that allows you to hook other gear and accessories to the outside for easy access (I use this for bottle openers and towels). I also love the MagShield magnetic closure which is easy to snap open and shut yet is strong enough to stay securely closed while you’re carrying it or tossing it in the truck.
Best Insulated: IceMule Boss 30L
Specs
Dimensions: 12.5” x 9” x 25”
Weight: 6.6 pounds
Capacity: 24 cans (without ice)
Pros
Excellent ice retention
Dry storage pockets are handy
Comfortable to carry
Cons
Price
Storage space is reduced by insulation
Most backpack coolers don’t have compartments that are designed for multi-day ice retention. However, the Boss 30L is the exception. It has some of the thickest polar plus insulation on the market. All that insulation reduces the storage capacity, of course, but this is the one to consider if you are looking for something for a multi-day camping trip. It can also function as a regular backpack in a pinch.
We like this cooler for surf or pier fishermen because it has two dry side pockets and a large front pocket—great places to safely stow a cell phone, camera, or other electronic device you don’t want getting wet. There are also loops for holding a pair of pliers, a net, gaff, or other fishing accessories. Our only knock against it is that it is a rather expensive cooler. However, it’s just right for those who need something a little more rugged with excellent ice retention qualities.
Best Small: Engel BP25 Roll-Top
Specs
Dimensions: 14” x 9” x 20”
Weight: 3.5 pounds
Capacity: 24 cans
Pros
Simple design with easy access
Generous storage capacity
Vacuum vale is a nice added feature
Cons
Price
Not many soft coolers have the generous 25-quart storage capacity of the Engel. This cooler has a very simple roll-top design and welded seams that help to keep the cold trapped inside and makes the cooler leakproof. The closed cell foam insulation allows for two to three days of ice retention.
We like this cooler for anyone who is rough on their gear. The outer shell is built of 840 denier fabric that will stand up to a real beating if you toss it on the ground, in a truck bed, or wherever. As a bonus, this cooler has a feature many other competitors do not: a vacuum valve that allows you to suck the air out and improve the efficiency of the insulation. It’s a nice little feature to have for a multi-day camping or kayak trip.
Best Waterproof: RTIC Backpack Cooler
Specs
Dimensions: 14.49” x 16.97” x 21.5”
Weight: 8 pounds
Capacity: 20 cans and a bag of ice
Pros
Affordable
Floats
Water- and leakproof
Cons
Zipper issues are common
For those who love the sand between their toes. The RTIC features a welded design with a zip-top to seal your food and beverages in the cold. It’s long enough to store a full-size wine bottle. We like this one for anglers too for the simple fact that it will float. No more worries about losing an expensive cooler over the edge of a pier or from your boat. That $170, this cooler packs in many of the leakproof features of a brand like Yeti at a fraction of the cost of other options on the market.
The only real downside to this cooler is the zipper, which a fair amount of customers say has issues with sticking. Most report they needed to lubricate it to make it easier to pull and to keep it from sticking. For the price point, that’s a small problem to overcome.
Best Budget: Bass Pro Shops Backpack Cooler
Specs
Dimensions: N/A
Weight: N/A
Capacity: 20 cans and 10 pounds of ice
Pros
Latch seal opens with one hand
Waist belt and sternum strap
Quality YKK zippers
Cons
Some users may not like the ridigity of the lid
There are cheaper backpack coolers on the market, but not many that offer the same capacity as the Coldsnap Latch. This cooler has a rather unique lid as far as backpack coolers are concerned. It is a rigid plastic with a single large snap that opens the interior for easy access. There is a bottle opener and some nice mesh side pockets for a little added value. Bass Pro Shops included some large, quality YKK zippers that are large, and easy to operate, and set this cooler apart from some of the others on this list. You should have no issues with these zippers getting stuck.
Some other nice features include a waist strap and a chest strap to help keep the cooler more secure during a difficult hike. For $129, this cooler offers a great deal of value that make it great for general purpose outdoor uses.
Best Storage Capacity: IceMule Pro XL
Specs
Dimensions: 14” x 11” x 24”
Weight: N/A
Capacity: 24 cans
Pros
Extremely large capacity
Air valve for added insulation
Easy to access contents
Cons
May not hold ice as long as other options
The Ice Mule Pro Xtra Large is the cooler for anyone who is looking for larger storage capacity. At 33L, this cooler will hold up to 24 standard 12-ounce cans with ice. This makes it an excellent choice for anyone who plans to take enough food and drink for the entire family. The roll top design makes everything in the large storage compartment easy to access quickly.
Ice Mule added an air valve to this model to help with the insulation this one provides. However, the downside to this cooler is that it may not retain ice as long as some of the other models on this list. We see this one as a great day hiking or boating option for larger groups.
How We Tested Backpack Coolers
When selecting the best backpack coolers, we considered our own hands-on experience with many of these brands. We also looked at other important factors when deciding which cooler is best for each scenario. Mainly we considered the following:
Materials: What is the cooler made from? Is it durable? Is it sustainable? Waterproof?
Storage Capacity: Just how much can the cooler hold? Is it strictly for food and drink, or can it be used as a regular backpack?
Ice Retention: How long is the cooler rated to hold ice?
Value: How budget-friendly is this backpack?
Buying Guide
The cooler you choose is usually best reflected based on how you plan to use it. Everyone wants the best ice retention, but you don’t need something that will keep for several days if you only plan to take your cooler to the beach occasionally.
If you are planning to do some serious hiking with your cooler, you’ll want to get something with the best padded straps. Your shoulders will thank you when the straps aren’t cutting in with the bulk of twenty pounds of ice in the back. The interior of the cooler must also be reinforced to be waterproof. The last thing anyone wants is to feel cold melting water down their back from a leaky cooler.
