Sigg

From their website:

Born in Switzerland over 100 years ago, SIGG today refreshes the world with stunning design and excellent quality. Its Swiss-made, reusable aluminium bottles are much more than drinking vessels. They are artists’ canvases with some masterpieces earning a place in New York’s Museum of Modern Art. Their light weight and practicality qualify them as vital equipment for adrenalin-hungry mountaineers. With 100% recyclability, designs in new materials such as stainless steel, continual innovation and products for all ages and tastes, SIGG proves it has a real thirst for tomorrow…
