SIGG
A SIGG bottle is like no other on the market today. The bottles are extrusion-pressed from a one-piece aluminum blank, which results in uniform, seamless walls. Each bottle's interior is then sprayed with baked-on, taste-inert, food-compatible, stove enamel which is resistant to fruit acids and isotonic drinks.
The result - a high-quality drinking system for your leisure and sports use.
