If you’re out in the wilderness doing sporty activities, the last thing you want is a case of the trots due to guzzling some dirty water. This bottle is your saviour, using UV light to neutralise any bacteria inside the bottle in a mere minute. Each charge can purify 16 gallons of H2O. Sadly, it’s only available in the US at the moment.
