What makes The Coldest Water feel so magical?
The science & engineering behind the scenes.

Most products you have are average. We hate that. When we build a product, we look to re-think how we can do it better, colder and more superior. We are an elite team of engineers based in Naples, Florida working day and night to invent the coldest, most superior products. 5 years later, and many patents filed, the coldest reusable water bottles were born. Some call it 'game-changing' but we just want to build products we are proud of, that we love and use every day, which ultimately, create less waste for the planet.

Keeps the ice, keeps the H2O cold, best insulated bottle...


I've tried several so-called, keep 'em cold bottles, here in hot Arizona as a bicyclist. This is the first one that lives up to its billing. I put in ice water and an hour later, it still has ice in it! All the other bottles, including CamelBak's Big Chill and a host of others. This is in temps that are in the high 90's. I've had bottles that didn't even hold the ice in temps of low 70's.

Best bottle I've owned so far...


2 years later and this bottle is kicking ass. Still keeps my drinks cold all day long. I think this is the best water bottle I have ever purchased! I work outdoors in some extreme heat. I like a cool/cold refreshing drink and a durable bottle that fits in the holder on my Scag Patriot mower. I found it with The Coldest Water Sports Bottle.

This really IS the coldest water bottle!


This really IS the coldest water bottle! I like my water cold...really cold! I typically freeze my water bottles and drink the water as it melts. I usually have to trade the bottles out because they get warm before I have finished them. No more! In the morning I fill it to the top with ice then pour water over the ice. I continue to add water as needed throughout the day and I have still had ice in it the following afternoon!
