If your spring and summer calendar is packed with games, park visits, and days by the water, you're likely already thinking ahead about what you'll need to bring with you. If you're planning to eat and drink on the go, a portable cooler to keep everything cold is a must—and Amazon shoppers say this under-$40 backpack style is the one to own. 

Traditional coolers with handles may feel light initially, but once they're packed with drinks and containers they can become tough to carry. That's when an item with straps, like the Tourit Backpack Cooler that weighs just over 1 pound when empty, comes in handy. The cooler helps to keep food and drinks stored at the proper temperature for up to 16 hours. It measures 13 by 7.5 by 15.8 inches, and its large size means you can store up to 30 soda cans inside.

"Absolutely the perfect cooler for a day outing," shared a five-star reviewer who confirmed their drinks and ice packs stayed cold inside. They said they even noticed other people using the cooler, and that they "raved" about it, too.

The best-selling backpack cooler already has over 13,400 five-star ratings and hundreds of perfect reviews. Many shoppers highlight the bag's leak-proof liner and multiple compartments, which include the large main section as well as two zippered sections, two mesh side pockets, and even a bottle opener that's attached to one of the straps.

A different shopper who said they were eager to switch to a backpack cooler because they found traditional styles "difficult and awkward" to carry was impressed that the bag never leaked, even when a bottle of water spilled inside. They also added that "the size is perfect," as it held water, sodas, and snacks for their family of four on a beach trip.

"We bought this for Disney and I can't say enough good things about it," wrote another reviewer. They shared that they packed eight water bottles and multiple food items inside the main compartment "with room to spare." They also stashed additional snacks and first-aid supplies in the other pockets and said they found a "hidden compartment" in the strap that was perfect for their car key.

Whether you're planning a picnic, a day at the beach, or a multi-day camping trip, make this the year you stop lugging a heavy cooler around. Instead, lighten your load and buy a Tourit backpack cooler in one of six colors while it's on sale for $37.
