No Ice Refills, 10 Days of Chill | Patented PhaseTherma Insulation | Proven Results | Effort-saving Zipper | 14L & 28L Available
You’ve packed for the perfect weekend. Brought fresh ingredients, BBQ foods, drinks, snacks, and maybe even a bottle of wine for the night. But then reality hits…
Choose a soft cooler? By the next morning, your food’s floating in a warm, slushy mess.
Choose a hard cooler? It takes up half your trunk and needs a team to lift it.
But why should we have to choose? Why can’t one cooler do it all?
We built the one that finally does it right:
Most coolers rely on thick walls and foam insulation to keep things cool. But no matter how “premium” or “refined” the foam is, the best they can do is to slow down the speed of heat transfer, but not prevent it. After years of study and experiments, we invented our patented PhaseTherma™ insulation to fundamentally change how coolers work.
Instead of just blocking heat from the outside, PhaseTherma™ actively absorbs excess cold, stores it, and releases it in response to micro-level temperature fluctuations within the cooler. As a result, the interior of your cooler stays icy cold for an impressively long time, even with multiple lid openings.
Why?
Because Freezill stores cold energy within its walls. So even when warm air enters as you open the lid, it releases that stored cold back into the cooler, helping to fight off the heat and keep your items inside cold and fresh!
To ensure accuracy and fairness, we commissioned TÜV, a globally recognized third-party testing institution, to conduct a scientific evaluation.
The results clearly show that with just 5kg of ice, Freezill maintained an internal temperature between 29.5ºF and 40ºF (-1.4ºC to 5ºC) for approximately nine to ten days, keeping most of the ice solid during that period.
Even after Day 10, it continued to keep the interior significantly below room temperature, delivering reliable cooling well into the later days.
