While the SIGG bottle may look much like any other, it in fact packs a lot of high-tech. SIGG bottles are extrusion-pressed from a one-piece aluminium blank, which results in uniform, seamless walls. Swiss know-how has always played a key role in the bottle’s development. Devotion to precision and the will for top-quality manufacturing have always driven production of SIGG bottles. Imitation may be the sincerest form of flattery, which is why there have been many copies over the years – yet none of them can match what is and remains the original Swiss bottle.
