ICEMULE Boss Review: A Reliable Backpack Cooler for the Great Outdoors

ICEMULE Boss Review

In this ICEMULE Boss review, I’ll tell you everything you need to know about this heavy-duty backpack cooler. The Boss will keep your cold drinks ice-cold mile after mile, regardless of whether you’re camping in the middle of nowhere or taking a cross-country trip in your car.

Apart from reviewing the ICEMULE Boss, I’ll be comparing this cooler with the Yeti Hopper Backflip 24, ICEMULE Pro XL and Otterbox Trooper LT30. All of which are this product’s competitors. Read on to decide whether it’s the ICEMULE Boss or one of its competitors that should go with you on your upcoming trip.

The Summary

The ICEMULE Boss has a 3-centimeter thick insulation foam that helps it retain ice for days. Its top-loading enclosure allows you to load your contents with effortless ease and the high-end suspension system makes it a cinch to carry, even when it’s packed to capacity (up to 60 pounds). However, its steep asking price might put off some potential users.

Weight and Build

The ICEMULE Boss weighs 7.5 pounds. This makes it considerably heavier than the 4.9lb-weighing Yeti Backflip 24 and more than twice as heavy as the ICEMULE Pro XL cooler. However, despite being on the heftier side, this product isn’t difficult to carry (more on this in the comfort & support section).

Turning our attention to its build, the Boss is made of a waterproof technical fabric (whatever that means). It features welded seams to keep the weak points from coming off and its main compartment has a 3-centimeter thick insulation foam to keep its contents ice cool.

A top-loading pocket makes it easy to pack/unpack this product. The absence of a zipper might put off some users, but not me. I’ve used backpack coolers with zippers and witnessed how easily their zippers came off upon being treated roughly. That is one thing you won’t have to worry about with the Boss.

Two insulated and waterproof cargo pockets on the sides are big enough to hold one regular soft drink bottle each. The one on the front is bigger and could hold as many items as the other two combined. Unlike the main pocket, all three side/front pockets are protected by a zipper.

Ice Retention

The ICEMULE Boss can keep ice frozen for 3+ days. The reason I can say that with confidence is that I was lucky to be able to test it out in one of the southern states for a very hot week. The cooler made sure that the ice I had paced inside its main compartment didn’t completely melt into water for 3 days.

Most of the credit for its excellent ice retention goes to the 3-centimeter thick polar layer XT insulation foam. The foam is sealed inside the two layers (inner/outer) of the backpack’s main fabric and does a fine job of keeping any air or heat from leaking into this backpack cooler.

This product’s IM AirValve also deserves credit for its superb ice retention. Located on the left side, it lets you add air to the insulation layer, increasing its insulating capability. Then, once you’re done using the cooler, you could open the valve to release the air so that the cooler rolls up for compact storage.

Comfort and Support

The ICEMULE Boss is much easier to carry than its competitors. That is despite the fact that this product could carry more weight (24 cans with no ice) than the Yeti Backflip (20 cans with no ice). This product’s ease of carrying stems from its high-end suspension system.

It comes with double-padded shoulder pads that help distribute this product’s weight evenly across your shoulders. An adjustable stabilizer strap right across where your ribs would be will make sure that the backpack is secured snugly right across your waist.

Then come the adjustable hip belt and the padded hip pads. Both make sure that the backpack rests right on top of your buttocks, not too up to interfere with your ease of movement and not too down to become too cumbersome to carry.

Other Notable Features

Here are other stand-out features of the ICEMULE Boss:

  • Modular Lightweight Load-carrying Equipment (MOLLE). Used by militaries all over the world, the MOLLE system lets you attach multi-tools, knives, and other equipment to this backpack. This way, you won’t have to dig through this backpack’s pockets to reach for survival gear.
  • Tons of clip points. Ever headed out for a long day of fishing, only to remember that one of the backpacks containing the essential gear is left behind at the campsite? Thanks to this model’s bottom-facing clip points, the risk of you inadvertently leaving it behind is zero. 
  • 100% waterproof. To test this claim, I bundled several useless documents into its main storage compartment. Afterwards, I tipped it over into my backyard pool and applied pressure on top to ensure it stayed submerged for 30 seconds. Guess what? Everything inside stayed bone-dry.
  • Roll-down style lid. Most other backpack coolers you see on the market protect their main compartment with a zipper. This model, however, has opted for the traditional roll-down style lid. One that makes it easy to access items as you won’t have to fret with a zipper. 
  • 3-year warranty. The Yeti Backflip 24 is backed by a 1-year warranty. The ICEMULE Boss, however, is warrantied for three years. This means that, at the very least, you can count on this product to last for two years longer than one of its main competitors.
