SIGG wanted to reinterpret its original Shield bottle. Since the cap is a defining element, both functionally and visually, the key challenge was to rethink its design. After numerous sketches and concept explorations, we developed a solution that gives the bottle a more modern appearance without changing the characteristic functionality of the closure. By refining the overall form, the iconic character of the Shield bottle was preserved while introducing a more contemporary design language. The distinctive SIGG design language of soft, rounded forms combined with precise cut-outs is expressed more consistently in the new version. This creates a more coherent and contemporary design that integrates naturally into SIGG’s existing product portfolio.
