Taking care of the environment is SIGG's goal. That is why they offer sustainable alternatives to disposable PET bottles. They haven't just been doing this since the latest UN climate report, but for over 100 years. In their company, tradition and innovation go hand in hand - their drinking bottles have cult status and are always setting new standards. Even in times of change, SIGG remain true to their values and focus on quality, innovation, design and environmental awareness.

SIGG Switzerland Bottles AG was founded in 1908 by Ferdinand Sigg.
