SIGGs bottles are extruded from a single piece of pure aluminium for seamless, leak-proof durability. Sigg liner is one-of-a-kind and the true secret of the SIGG bottle. It is a proprietary formula which is baked on for the life of the bottle and remains flexible and crack-resistance despite how dinged up the outside of the bottle might get. The SIGG bottle liner is leach-proof and resistant even to energy drinks, fruit acids and carbonation.

For over 100 years now, SIGG bottles have been expertly manufactured in Switzerland.
