Imagine hiking all day in direct sunlight, 85 degrees out, you just smashed a 2500 foot elevation change before lunch and your feeling fresh. You reach into your bag and triumphantly pull out….

A warm bottle of water or beer. Gross.

Lugging a cooler around is difficult, cumbersome, and who’s going to take a cooler on a hike? For sure not me.

Finding the best backpack cooler is the jam, the best of both worlds. Now instead of lugging around a cooler all day or warm beers in your pack, you can carry them in an insulated backpack that will keep ’em on ice.

What is a backpack cooler?

The ideal backpack cooler is going to be lightweight, comfortable, and will retain ice all day, preferably 24 hours.

When shopping for anything, looking for the best deal without sacrificing quality is the ultimate goal. There are different styles of backpacks that are intended for different uses. Some styles are better for day hikes, some are better in water, and others are half-cooler and half-backpack.

Different backpack coolers are designed for different purposes, therefore the specs will vary widely based on the model you choose.

Backpack cooler features

A backpack cooler serves three main purposes. It should be well-insulated, large enough to meet your needs, and comfortable.

Ice retention

The main reason you buy a cooler is to keep things cold and ice retention is where the magic happens. This is the amount of time that the backpack cooler will retain ice before it completely melts. Ice retention rates can vary from 6 hours to 24 hours. Heat rises and cold air sinks, so keep this in mind when loading your backpack. You get the most out of your crushed or block ice by packing first and then setting the supplies on top of the ice.

Constant opening of the pack lets heat in and gives the cold air a chance to escape. Limit the number of times you open the pack throughout the day. Place things you might need quick access to on top of the ice so you can get it out quickly.


The capacity of the cooler you choose will depend on what you plan on using it for and they are often measured in cans. Backpack coolers come in a variety of shapes and sizes. Everything from a small cooler just large enough for your lunch to a pack that holds a case of beer and more. Another thing to consider about capacity is the pockets on the outside of the pack that gives you extra storage. Most of the packs have mesh pockets for extra bottles, and a zipper pocket for personal belongings.


If cooling is the first concern, comfort is a close second. The last thing you need is to figure out that a pack sucks 12 hours into a 3-day scramble, it will hurt and you’ll be miserable. Carrying around drinks and snacks all day long can become uncomfortable quickly. Consider the shoulder straps and padding, especially if you plan on taking an overnight hike.

At 18 x 12 x 7, you have plenty of space for cold beverages, ice, and snacks.

It has a wide opening, larger than other styles making getting things in and out a breeze. Some of the coolers have a smaller opening on the top and it can be a hassle to get all the way to the bottom.

Coleman C003 Soft Backpack Cooler

Coleman C003 Soft Backpack Cooler
6,548 Reviews
Coleman C003 Soft Backpack Cooler
  • INSULATION: Main compartment keeps contents cold and prevents leaks with heat-welded seams
  • CAPACITY: Holds up to 28 cans
  • EASY TO CARRY: Backpack design with adjustable padded straps for maximum comfort
  • EXTRA STORAGE: Large front pocket for quick access to napkins and accessories

With a heat welded cooler you can throw all the ice you want and not have to worry about it leaking out of the bottom. When the ice begins to melt water will begin to leak out of the zipper if you tip the pack over too far, just keep an eye on it or use sealed ice. Easy peasy.

The manufacturer says that the capacity is 28 cans, but according to some reviews that number is misleading and 12-16 cans is the actual number. The shoulder and waist are reinforced with extra padding, making carrying heavy loads easier on your shoulders and back. There’s two zippered pockets on the sides and one in front. The one in front will get cold if you fill the Coleman C003 with ice, so be careful with anything like a cell phone in the front pocket.

This backpack is awesome for a one-day outing, is has decent insulation, and awesome support. The extra padding on the shoulder straps and the waist clip displace the weight of the pack making carrying it a breeze.

  • Ice retention: 10 hours
  • Capacity: 28 cans
  • Color: Brown
  • Weight: 2.5 pounds
