10 Best Insulated Backpack Coolers 2026 in the United States

The YETI Hopper M12 Backpack Soft Sided Cooler stands out with its impressive ability to carry up to 20 cans of beverages or 12 pounds of ice, which speaks well for its capacity. The MAGSHIELD ACCESS feature ensures the cooler is ultra leak-resistant and easy to use, which is a significant advantage for users on the go.

Additionally, the COLDCELL INSULATION ensures that contents remain cold for extended periods, which is crucial for outdoor activities like camping and hiking. The DRYHIDE SHELL adds to the cooler’s durability, making it resistant to punctures and UV rays, a thoughtful inclusion for those who frequent rugged environments.

The kangaroo pocket adds convenience, allowing users to store small but essential items such as phones, keys, or wallets securely. However, the cooler's weight might be a downside for some, as it weighs over 3 kilograms, which could be cumbersome for long treks or when fully packed. Comfort and fit are essential for backpacks, and while the YETI M12 offers hands-free convenience, some users might find the dimensions (8 x 17 x 16 inches) bulky or challenging to fit their personal comfort. Despite these minor issues, the YETI Hopper M12 is an excellent choice for those who prioritize durability, insulation, and the convenience of hands-free carrying in their outdoor adventures.

The YETI Hopper M20 Backpack is a well-designed insulated cooler backpack, ideal for outdoor activities like hiking where you want to keep your hands free. It offers a capacity of 6.3 liters, which fits about 18 cans or 26 pounds of ice—enough for a small group or a day trip. Its ColdCell insulation uses closed-cell foam, which does a solid job keeping your drinks and food cold for hours. The DryHide shell adds durability, resisting punctures and UV damage, making it tough enough for rough outdoor use. Weighing around 3.4 kilograms (7.5 pounds), it’s not the lightest option but still manageable for its size and insulation level.

Comfort and fit are priorities here, with multiple carry handles and backpack straps designed for ease during hikes. A standout feature is the MagShield Access, a magnetic seal that prevents leaks and stays open when you want it to, which is convenient and helps keep contents secure. The HitchPoint Grid allows attaching accessories like side gear or bottle openers, adding useful customization.

A potential drawback is that the capacity might feel a bit small for longer trips or bigger groups, and the weight could be noticeable if you’re carrying it all day. The price tends to be higher compared to basic coolers, reflecting its premium build and features. The YETI Hopper M20 is an excellent choice for those who want a durable, reliable backpack cooler with excellent insulation and smart features, making it best suited for day hikes or outings where portability and keeping items cold matter most.

The SPARTER Backpack Cooler is a solid choice for anyone needing a portable and efficient way to keep beverages cool for up to 20 hours. With a capacity of 30 cans (12 liters), it’s spacious enough for meals, drinks, and snacks, making it ideal for beach trips, camping, hiking, and other outdoor activities. The 8 mm foam insulation and advanced silver PEVA seal contribute to its impressive cooling retention.

However, while the liner is leak-proof, the zipper isn't, so you need to be cautious about tipping it over to avoid spills. The backpack is lightweight at only 1.13 pounds and made of high-density, scratch-resistant nylon with a waterproof PU coating, which enhances its durability. Comfort is addressed with padded shoulder straps and back, but the fit can vary depending on individual preferences.

Additional features include two insulated compartments for separating cool and dry items, multiple pockets for accessories, and a convenient beer opener. Despite its many strengths, users should note that it requires careful handling due to the non-leak-proof zipper. It's well-suited for those who need a versatile and easy-to-carry cooler for various outdoor adventures.
