About SIGG The history of SIGG started back in 1908, when Ferdinand Sigg, together with his friend Xaver Küng, founded a factory of aluminum production in the city of Biel in Switzerland. Sigg and Küng combined their love of metal and their faith in aluminum as the material of the future. SIGG's refillable, lightweight, and environmentally friendly beverage bottles have been manufactured in Switzerland for over a hundred years under strict quality control. Each classic bottle is made of one aluminum component, so there are no seams that could leak in the finished product. Aluminum is a very durable and light material. Thanks to SIGG's patented and flexible EcoCare® inner coating, you can put carbonated drinks in your SIGG bottle without detaching anything from the aluminum. The inner surface doesn't collect odors or flavors, and the bottle is easy to keep clean. The bottles are recyclable, BPA-free, and approved by the food authorities.
