Sigg Switzerland, which has produced aluminum drinking bottles for more than a century, will be entering new product categories. The brand presented its complete stainless steel thermo collection for the first time during the OutDoor show in Friedrichshafen. The prototype of the thermo collection made from stainless steel was presented at the Ispo 2013 in Munich at the beginning of this year, but Sigg now presented the full line, which includes four different sizes. The thermo line will be available in the stores from October 2013. The newest product category, which has been added by Sigg, is a collection of transparent plastic bottles made from polypropylene. The latest product category is manufactured in Sigg's own factory in Switzerland and is the first one, which does not come in Sigg's original design, but with a flip-top bite valve.
