It is important to drink filtered water to avoid getting sick and to continue your trekking week without any issues. When you are at home or in society, nothing is easier; you just turn on the tap! But things get complicated once you head into nature or into countries where potable water is less accessible. That's when the Go Tritan ReGourde Lifestraw comes into play. This bottle allows you to filter up to 1,000 L of water (the filter clogs when it reaches its limit). This filtering bottle eliminates 99.9999% of bacteria and 99.9% of protozoa. You will never run out of safe drinking water with the Go Tritan ReGourde.
