The Science Behind
Staying Cold
Most people accept warm drinks and melted ice as part of the deal. 4EVER-ICE® was built to change that — and here's exactly how it does it.
The Science Behind
We all have one thing in common — we all buy ice.
Simple. Proven. Effective.
Ready in 3 Easy Steps
No complicated setup. No special equipment. Just prep it the night before and let the science do the rest.
1
Fill & Freeze
Your 4EVER-ICE® bottle comes pre-loaded with the KoolerGel® mixture. Remove the cap and plug, fill with cold water to the marked fill line, replace the cap, and give it a good shake. Then place it in the freezer at optimum temperature (5°F to -10°F) for 24 hours. The fill line is intentional — it gives the mixture room to expand as it freezes, keeping the bottle sealed and leak-free.
🕐 Best frozen overnight before your trip — cold water freezes faster
2
Drop It in Your Cooler
Set your frozen 4EVER-ICE® bottle in the bottom of your cooler and add one bag of ice on top. As the ice starts to melt, it refreezes against the bottle — creating a growing block of ice that has to thaw from the outside in. Your ice lasts up to 50% longer. Most customers see even better results.

Refreeze, Reuse, Repeat — For Years
When the fun's over, rinse it off, put it back in the freezer, and it's ready for the next adventure. 4EVER-ICE® is built to be reused hundreds of times. One purchase pays for itself and keeps on giving — every single outing.
The Science
Why 4EVER-ICE® Holds Cold Longer
Here's what makes 4EVER-ICE® genuinely different — and it comes down to one thing: back-end performance.
Most cooling products work great at the start. But when you look at how long they actually hold that temperature, the results tell a very different story. 4EVER-ICE® is engineered around that back-end performance. Once it reaches 31.5°F, it stays there for up to 18 hours before beginning to thaw.
Regular ice starts melting the moment it hits 32°F — no hold, no buffer. A standard 2-litre bottle of frozen water lasts roughly 11 hours at 71.5 degree room temperature. 4EVER-ICE® holds its temperature significantly longer, because it isn't just frozen water. It's a patented formula engineered to lock in cold and release it slowly over time.
4EVER-ICE® — Holds at
31.5°F
Once frozen, 4EVER-ICE® holds at 31.5°F for up to 18 hours before beginning to thaw — giving your cooler a long, sustained cold zone that outlasts the ice around it.
2L Water Bottle — Thaw Time
~11 hrs
A standard frozen 2-litre water bottle lasts roughly 11 hours at room temperature. 4EVER-ICE® holds its cold significantly longer, thanks to the KoolerGel® formula.
Regular Ice — Starts Melting at
32°F
The moment regular ice reaches 32°F, it starts to melt. There's no temperature hold, no buffer — it's melting from the moment it starts to warm up.
