Every SIGG bottle is a small testament to Swiss craftsmanship, and has been for over 100 years. And the Swiss Culture series was created to celebrate this success. The high-quality recyclable aluminum bottle is extremely light, durable and can be carried comfortably, for example hanging on one finger - even in the liter version. It is 100% leak-proof, even in the case of carbonated drinks. The material does not contain harmful chemicals such as estrogen mimics and phthalates. The inner surface is treated with a special patented EcoCare technology, which is safe for health and hygiene, does not absorb any odors or tastes and flexibly adapts to a new shape when the bottle is dented. By using SIGG bottles, you reduce your ecological footprint - you protect the environment!
