Feather-light aluminum is the basis for the Sigg water bottle: a high performance alternative to plastic water bottles for sport and leisure. The body of the bottle is extruded form a single piece of seamless pure aluminum with a taste-neutral internal coating. The screw top features an integrated seal that is leak-proof, even for carbonated drinks. 100% recyclable. If all this isn't Swiss enough for you, the graphic treatment should do the trick.
