While spring break season depends on your location, it's safe to say that no matter when yours is, a beach trip is a must. You'll need a swimsuit, sunscreen, sunglasses—and a beach bag to carry it all. If you're planning for a whole day affair, you'll want to pack water and snacks too. And Amazon shoppers have found a clever beach bag that has a secret cooler underneath to keep beverages and snacks perfectly chilled for just $30.

The OdyseaCo Aruba Mesh Beach Bag Cooler is the two-in-one tote you never knew you needed. The 20-inch deep bag can hold both small and large beach essentials, including towels, a change of clothes, books, and portable speakers. Each item has a home thanks to its two pockets on the outside as well as a zippered area inside for your keys or phone.

To buy: $30; amazon.com. 

However, the star of the show is truly the hidden cooler located at the bottom of the bag. The insulated compartment keeps perishable items and drinks cold for hours. In fact, one shopper who packed chilled soda cans and fruit in it for a road trip said, "Everything was still cool when we got there (11 hours later)." 

Reviewers love its large-capacity design, too. One person said there was "more than enough room" to store several Gatorade bottles and applesauce packs, while another who stored six cans of beer, four juice boxes, multiple sandwiches, grapes, and ice in the bag said "The insulated bottom fit much more than I expected it to" and called it their "new favorite beach/camping accessory." 

What makes the bag especially ideal for the beach is its mesh design that allows air to filter through, allowing wet swimsuits and damp towels to dry better. And because you'll probably lounge on the shore with the kids or sunbathe, you'll love that the mesh construction easily lets sand out, too. This way you won't be bringing home the entire beach with you—and it's a major reason why people call it a "must-have."

This beach bag secures all your belongings with zippered closures and is made with a padded handle and an adjustable shoulder strap. It comes in five colors, including neutral black, bright blue, teal, and a star-patterned pick as well as a fun striped option. It's also worth noting that shoppers suggest packing the cooler first before filling up the top to prevent the bag from toppling over when it's placed on the ground or any other surface.

While the cooler bag is designed for the beach, reviewers have also taken it on camping trips, to the pool, school sporting events, picnics—you name it. It's no wonder the bag has earned more than 1,700 five-star ratings on Amazon so far. A fan who said the cooler is "deceptively large." called it a "super convenient all-in-one bag."

Don't leave for vacation without this versatile insulated cooler bag that's just $30 on Amazon.
