On a hot summer day, there's nothing like an ice cold drink to quench your thirst. A quality insulated water bottle makes it easy to keep refreshing drinks with you at all times, but they can be surprisingly expensive. 

That's why you need to know about this Amazon shopper favorite: the Mira 17-ounce insulated bottle. Users say it keeps beverages ice-cold for hours and is a must-have for days when it's tough to beat the heat. It's also typically a fraction of the cost of name-brand bottles, and you can even get it for as little as $12 right now.

To buy: Mira 17-Ounce Stainless Steel Vacuum Insulated Water Bottle, $12 (originally $14) at amazon.com

The BPA-free bottle — insulated with stainless steel and sturdy vacuum seal lid — can keep your drinks cold for 24 hours and hot for 12 hours, making it the ideal companion for any busy commute or adventure. It also has a sweat-proof exterior, so you can keep it stowed in your bag or backpack without worrying about any of your other items getting wet. 

The 17-ounce size is large enough to keep you hydrated without the annoying weight of a bulky bottle. Plus, the design (which comes in colors like lavender, olive green, and matte dark blue ) is slim enough to hold comfortably or fit in cup holders.

Thousands of Amazon reviewers have given the Mira bottle a perfect rating, with several praising its leak-proof design and insulation. One shopper who purchased the bottle for vacation in Costa Rica found the water stayed cold for over nine hours despite the hot and humid weather. They went on to write that they use the bottle daily. 

"It exceeded my expectations," one said, adding that it's the perfect size and color, as well as that it's easy to clean. Many have also compared the bottle to popular insulated drinkware brands like Hydro Flask, Yeti, and S'well. "I have a few Yeti and Ozark stainless steel cups and thermoses that I love, but I'd rank this right up there with them," a user said. Another reviewer wrote, "I love that the Mira bottle is half the price as the S'well bottles and is just as good in quality, if not even better." 

Whether you're trying to beat the heat or simply need a bottle to carry with you through your day, you'll want to add this to your cart. But hurry — only select colors are on sale, and we're not sure how long the discount will last. Purchase the $12 bottle at Amazon now.
