The proof
The original since 1998. Every number on this page has a source: the measurement by Dermatest GmbH in Münster, a US Marines field test and the letters from the teams that cooled with it.
Dermatest GmbH · Münster
Measured on the soaked bandage: 5.8 °C cooler skin.¹
Dermatest in Münster did the measuring: 20 subjects, contactless infrared, for two hours. They tested the soaked bandage.
Evaluated and signed by two specialists in dermatology.
Two numbers, one source. The charts show the curve schematically, with no extra values.
Measured on the inner forearm, contactless by infrared, against the skin’s baseline before application.
Why it matters
Cools like sweat: by evaporation. No ice, no power.
Seven measuring points over 120 minutes. The skin stayed cooler than before for the whole measurement.
What that means for you
Apply generously, onto fabric. The soaked bandage is what was measured; a light mist on a shirt wears off sooner. When it warms up, just spray again.
A real thermal camera, five body areas. Each after 20 minutes with the soaked bandage, taken right after it came off: blue is where the bandage was.

Measuring is one thing. Liquid Ice has been worn where it gets hot: in Formula 1, at the Ice Hockey World Championship, at the Tour de France. Every card names its source.

Formula 1
“The pilot asked for the Liquid Ice treatment after our regular warm up, just before the race start. … He was alert and concentrated throughout the whole race and stayed cool even under enormous mental and physical pressure. Even under these conditions it is so important to use Liquid Ice to save energy, keep calm not cracking under pressure and stay focused for a long time.” Felipe Nasr finished ninth, Sauber’s only points of the 2016 season.

Dermatest GmbH in Münster, an independent testing institute: 20 subjects, contactless infrared measurement on the inner forearm, 120 minutes.
Skin temperature on the inner forearm, applied with the soaked bandage, compared with the baseline before application. Measured: 5.8 °C cooler skin. Still cooling after two hours.
The soaked bandage is what was measured. Sprayed onto a shirt, the same liquid cools the same way, by evaporation. How long depends on how generously you spray: a light mist wears off sooner, and you can spray again any time.
The Dermatest test showed no unwanted skin reactions. Still: best on fabric, don’t spray large areas of bare skin, and avoid contact with eyes.
Olympic teams from ten nations in Athens, the Leopard-Trek cycling team at the Tour de France, three-time Le Mans winner Marcel Fässler, the US Marines in a field test (9.1 out of 10 for ease of use), a Lamborghini Super Trofeo team and many people who work or train in the heat. Shipped to 20+ countries.
