The classic bottle – reinvented! Made from a single piece and inspired by the archieves of SIGG, we have reissued our original form. A modern metal closure with a carrying handle, a wider opening and easy cleaning are the values of the Original bottle. It is 100% leak-proof even with carbonated drinks and when held upside down. The material is free of harmful chemicals, such as estrogen-mimicking substances and phthalates. The multi-layered inner liner holds up a lot of stress (eg bumps) and guarantees a safer drinking experience.
