For over 100 years, SIGG bottles have utilized Swiss precision and craftsmanship to produce high-quality aluminum, reusable bottles. A USA subsidiary was launched in 2005, but SIGG operations still remain in the quaint village of Frauenfeld, Switzerland to this day. Their factory meets the highest environmental standards in Switzerland, one of the most environmentally responsible nations in the world. SIGG water bottles have been independently tested to be 100% free of BPA, phthalates and other harmful chemicals. Each SIGG water bottle is a safe, lightweight, durable and stylish alternative to disposable water bottles.
