frank green Ice Test
The science behind the sip

Why we're doing this
After years of design, testing and tweaking, we back our Ceramic Reusable Bottles to stay cooler, longer. So we’re proving it.
Just a test to show what premium really means.
1. Triple wall vacuum insulation
- To keep your water icy for longer
2. Durable stainless steel
- Built for thousands of icy refills
3. Spill resistant lids
- Keeping your icy water in your bottle
4. Built to last and built to perform
- Shatter proof design to keep your icy water secure
This is what happens when good design meets cold science.
How we’re testing it
We filled our biggest bottle with ice and hit record.
It's a thermometer and a whole lot of waiting.
We’ll stop the test when the water hits 4°C, the temp of a fridge chill.
