From the brand Stays Colder, Longer, our mission is to build the COLDEST products so you stay cool longer. Founded in 2015 by an elite team of engineers in Naples, Florida, our humble beginnings started in a 1 car garage working day and night to craft the best, coldest things. Today, many customers are still using the same product they bought 7 years later. By focusing on building the best, COLDEST products, they not only last you longer, but create less waste for the planet.

The Coldest Water Flip Top Insulated Cap, which is finally here after 3 years, was initially built for Professional Athletes in high-performing sports. We believe in taking cold water on the go wherever you are, whether you are biking, cycling, running, jogging, or going to the beach. This cap allows you to drink effortlessly with one hand. Simply flip the top, and drink water from it.

The flip-top has a unique tab that allows you to push it without your fingers touching the mouthpiece, making it a more hygienic option. We believe in multi-compatibility, so we've extensively tested this with The Coldest Water Bottle, as well as other Stainless Steel Bottle Brands. We believe in creating products that will last you a very long time, while keeping your activity at its peak performance.

The Coldest Water Insulated Standard Mouth Cap, Patent Pending, was also initially built for Professional Athletes in high-performing sports. This cap allows you to drink effortlessly with one hand, and includes two straws, a straw cleaner, and a 2.0 lid. Customers may need to cut the straw to fit your size bottle, and the upgraded design provides the best flow rates for your hydration needs.

We believe in multi-compatibility, so we've extensively tested this with The Coldest Water Bottle, as well as other Stainless Steel Bottle Brands. The cap is verified compatible with The Coldest Water Bottle, HydroFlask Standard Mouth Bottles, Klean Kanteen Classic Mouth Bottles, Rehydrate Pro Standard Bottles, and WaterVault Water Bottle 24 oz Only* Bottles. It may also be compatible with other Stainless Steel Bottles with a 1.75-inch inner screw mouth diameter, but is incompatible with Hydroflask Wide-mouth Bottles, Hydroflask Narrow-mouth bottles, Widemouth Bottles, and Narrow-mouth bottles.

What makes The Coldest Standard Mouth Lid feel so magical? The science & engineering behind the scenes. We are an elite team of engineers based in Naples, Florida working day and night to invent the coldest, most superior products. 6 years later, and many legal things filed, The Coldest Standard Mouth Lid was 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.
