frank green Ice Test

The science behind the sip

Why we’re doing this

We care a lot about performance. That’s why we invest over 40,000 hours every year into designing, testing and refining every single frank green product.

It’s no accident our bottles go the distance. They’re the result of relentless innovation and world-class engineering.

Now we’re showing you what all that effort really looks like.

1. Triple wall vacuum insulation

  • For maximum chill, minimal melt

2. Premium stainless steel shell

  • Engineered for endless icy refills

3. Spill-resistant lids

  • To keep your cold locked in

4. Ceramic lining

  • Designed to resist extreme heat and preserve temperature, whilst preventing that metallic taste.

5. Built to last, built to perform

  • Performance you can feel

We don’t just make bottles. We make them better, every single day.

How we’re testing it

We packed our 2L Ceramic Reusable Bottle with ice and hit record.

Just a Bluetooth thermometer and a whole lot of patience.

We’ll stop the clock when the water hits +4°C, the temp of cold water in your fridge.

We Have a Winner

Congratulations to our winner Kirsten, whose guess of 7 days 6 hours was closest in our Ice Test challenge.

They’ve scored themselves a frank green Ice Test prize pack.
