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 Bottle, The Coldest Pillow, The Coldest Ice Packs 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.  ...Read full story

David, Engineer & Founder

The Coldest Beach Cleanup Initiative

The Coldest Beach Cleanup Initiative was founded to improve our beaches, waterways, and oceans while meeting others and networking. 

The oceans face a massive and growing threat from something you encounter everyday: plastics. An estimated 17.6 billion pounds of plastic leaks into the marine environment from land-based sources every year—this is roughly equivalent to dumping a garbage truck full of plastic into the oceans every minute.

Every month our team, together with Coldest Volunteers around the world dedicate hours, resources, & technology into removing plastic from our oceans. Learn more
