Can the Shark Tank Water Bottle Really Keep Drinks Cold for 36 Hours? I Tested One to Find Out
Here’s how long a Coldest water bottle keeps things chilled compared to my go-to mug.
The Coldest water bottle, a newcomer to the hydration scene that boasts a claim of keeping drinks cold for 36 hours, piqued my curiosity. The company, hailing from Naples, Florida, even made an appearance on ABC’s "Shark Tank," and its products have been featured in national media. With a range of sizes, styles, and limited-edition designs, the Coldest brand has clearly put effort into its marketing.
However, I decided to put the bottle to the test to see if it truly lived up to the hype. For the experiment, I compared the Coldest to my own trusted $30 Owala water bottle, both filled with equal amounts of water and ice. While both bottles provided ice-cold water initially, the Owala consistently maintained a colder temperature than the Coldest after a few hours.
Throughout the 36-hour duration, the temperature difference between the two bottles only seemed to narrow, with Coldest ultimately holding a slight advantage due to its larger size. Despite the promising marketing and the company's success in generating a cult-following through limited-edition designs, I found the Coldest water bottle to be neutral in my opinion.
While the variety of designs and features may appeal to a specific subset of consumers, the overall performance and cooling capabilities fell short of my expectations for a must-have hydration accessory.
