These water bottles are functional, fashionable and super light. Dopper is a Dutch brand founded by Rinke Van Remortel who, in 2013 received the Red Dot Design Award for his contribution to the society and environment well-being. Every year, almost 8 tons of plastics get to the sea putting it and its habitants at risk. The Dopper water bottle can be used several times without wasting, as it totally recyclable. In addition, it is safer that normal plastic battles as it doesn't cointain BPA and phthalates...that's why 20% of Dutches always carry their Dopper them. In addition, 5% of the income goes to the Dopper Foundation that invests in projects that aim at bringing water to poor countries. A small thing for men but a huge one towards saving the oceans!
