The VIVA NAT bottles by Sigg take another step combining classic outlines of the popular Sigg bottles with the advantages or modernity.
The Viva bottles have the NAT top (New Active Top) like all the other NAT bottles by Sigg: The high-tech lid has a safety valve and a pre-ventilation mechanism in order to grant maximal comfort. The new technique with the included drinking straw makes drinking fluid without the need of tilting the bottle. The pre-ventilation mechanism avoids spilling around and the variable rate of flow is responsible for fast thirst quenching.
The closure is leak-proof, even if the NAT bottles of Sigg are upside-down. This is good for kids, sportsmen and drivers. Since it isn’t necessary to open the bottle anymore. This makes it possible to drink without any problems, non-stop. So to say, the Swiss re-invented drinking with the NAT bottle.
Drinking bottle of a new generation
Sigg produces the NAT bottle out of polypropylene in the VIVA edition: The Swiss manufacturer chose the longevity material for this new generation bottle considering the tradition of their research and the huge development time of it. Polypropylene is adapted to the strict safety and sustainability standards, given by the manufacturer to itself.
All the parts of the bottle are easily demounted and cleaned in the dishwasher. It is only natural for the bottles of the manufacturer to be free of pollutants, recyclable and sophisticated. The New Active Top of the bottle can be replaced by all the other tops of Sigg with the optionally available WMB adapter.
