I Put a Coldest Water Bottle to the Test, Here’s What Happened

You’ve seen them in ads, you’ve seen them on social media influencer posts, you’ve even seen them in viral comedy videos on Facebook, so are they a scam, or are they truly worth the hype? I put a genuine Coldest water bottle to the test against another big name in the reusable bottle game. The results were truly surprising!

So what’s the claim in the first place?

”UP TO 36 HOURS COLD, 13+ HOURS HOT,” according to their marketing. All of the reusable bottle competition have similar claims, of course. Living in steamy jungle-like Florida, you learn the value of the cold for many hours feature. I didn’t even have to document a full 36 hr experiment before I was confident enough to start writing this blog post!

The results speak for themselves

9:30 am: I load 12 fully formed ice cubes into both the Coldest bottle and a Takeya bottle. note, Takeya claims up to 24 hours of ice cold water. I seal both bottles, making sure they are both hand tight and the drinking pieces are firmly shut. I set them in a spot in the kitchen with no sun, hardly any natural light at all really, and then I waited... I waited exactly 25 hours. Over that time my house temp ranged from about 68-76 degrees.

10:30 the following day: Left completely unopened, I was expecting that both bottles would still have ice in them. To my surprise, there was not a single cube left in the Takeya, and the water was only slightly cooler than the room! The Coldest bottle, however, still had individually distinguishable cubes in it! It was in fact the coldest. Shortly before writing this, now a full 48 hours later, I poured the Coldest bottle out into the sink over my hand, and I’ll be damned the water from the melted ice was actually still cold.

What else sets Coldest bottles apart and why does a sustainability blog like them?

I spoke to a coldest founder to get to know the story of the company and learn about their goals for the relatively new name in a sea of competitors. Firstly, we love a local company - Coldest is based in Fort Myers, Florida. Although their manufacturing is not currently in the US, they employ a team of people in the states that is growing with their business, along with an affiliate program. The affiliate program allows folks like me to earn a piece of the growth pie by sharing first hand experience backed posts like this one. If you’re interested in joining as an affiliate, click here.

Even more to love, in an effort to increase their sustainability, Coldest offers “Mystery Boxes” which are not unlike the scratch and dent outlets you see for high end appliances with mostly unnoticeable flaws. The boxes are valued over $150 but only cost $50! What a great way to reduce waste! Presently, Coldest is working on a project involving recycled materials, look out for more details on this in the near future!

In conclusion, Little Seeds Grow Big Trees names the Coldest company an honorary “little seed” of its own for their BIG work in reducing the use of plastic water bottles, and their ongoing research into becoming an increasingly sustainable company.
