'Way better than a Stanley': Amazon's No. 1 bestselling water bottle is just $21

You might think you're all ready for summer with your new swimsuit, sunscreen and shades, but there's one essential you should make sure you have before those heatwaves hit — a sturdy water bottle. Yes, it's important to stay hydrated all year long, but drinking enough H2O is even more crucial on those scorching hot days. We've got just the ticket: Amazon's No. 1 bestselling Iron Flask Water Bottle. This insulated vessel keeps your drinks cold for up to 24 hours and conveniently comes with three leakproof lids. Oh, and right now it's on sale for just $21 — take that, splurge-y Stanleys!

Made of durable BPA-free stainless steel, the Iron Flask was built to last without leaving a metallic taste in your mouth. Its double-walled insulation not only traps the ideal temperature for whatever beverage is in it — drinks stay cold for up to 24 hours and hot for up to 12 — it also prevents that dreaded condensation sweat. Clammy hands are so last season.

What really sets this thirst-quencher apart from the rest is that it comes with not one, not two, but three lids — and they each suit different drinking styles. There's a carabiner lid that includes two straws, a flip-lid that keeps your drink covered but easily accessible and a screw-on stainless steel lid, which lets you take a big ol' swig from the mouth of the bottle. All are leakproof, meaning you can throw the tumbler in your bag without worrying about it turning into a soggy mess.

If you're someone who has trouble remembering to stay hydrated (raises hand), having a cute water bottle can definitely help with motivation. Luckily, the Iron Flask comes in 28 gorgeous hues, from brights and pastels to neutrals and fun prints (prices vary). While the 32-ounce bottle we're linking to will require an expandable cup holder, it also comes in three smaller sizes that'll fit most standard cup holders just fine.

More than 107,000 Amazon customers are so smitten with the Iron Flask, they gave it a perfect five-star rating. Some even rave that it's better than its pricier rivals. "Great water bottle!" exclaimed a happy shopper. "Way better than a Stanley cup in my opinion."

"Perfect for me!" wrote an impressed reviewer. "Some of the brand names can be very expensive. For the same thing, this bottle fills all your needs ... And you can’t beat this price. I fill it with cold water in the morning and leave it in the car all day, and it is still cold when I want it at the end of my workday. Despite being left in the car in Florida!"

"This water bottle has become something I never leave the house without," gushed a satisfied sipper. "Keeps water cold for days and I throw it in my purse all the time — it never leaks! I’ve had three of my friends purchase since I got mine — you will not regret it."

"I’ve finally found the water bottle," announced a final fan. "I keep this in my purse and the water is still cold, even by the end of the day! And it doesn’t sweat, so I don’t have to worry about condensation getting on things inside my purse. It has several options for lids, but I’m using the straw-type and it’s very easy to open and close. Even my child, who is notoriously picky when it comes to drinking containers, will drink from this bottle. Success! Will definitely be purchasing a few more."
