Grayl

Founded in 2012, Grayl is an American brand based in Seattle, specialising in portable water purification systems.

Grayl is the result of hundreds of nights camping in the most remote places on the planet and thousands of hours in developing countries. Their goal? To enable self-sufficient expeditions. After seeing, experiencing, testing and working in these places where access to safe drinking water is difficult, the first Grayl water purifier was born.

Today, Grayl water bottles with integrated purifier are the most versatile on the market. They are both simple and quick to use. Most importantly, they eliminate bacteria and protozoa as well as viruses. Whether you're faced with a stream of murky water or in a dodgy hotel, fill up with water with complete peace of mind.

The principle of these bottles (Geopress and Ultralight Compact) is simple: fill, press and drink. In seconds, turbid and unsafe water becomes clear and drinkable.

To top it all off, the Californian brand donates 1% of its revenue to environmental organisations. In short, Grayl is an innovative and committed brand.
