Leak-proof and sustainable. The Sigg Shield One water bottle is the ideal companion for all leisure activities, whether at sports, in the office, or at school. It impresses with its high-quality design. The One Top protects the mouthpiece from dirt and dust and allows for one-handed operation: this applies to carrying, opening, drinking, closing, and securing the bottle. Additionally, the leak-proof water bottle is suitable for carbonated beverages. The extra-large opening aids in cleaning and filling the bottle, making it easy to fit ice cubes inside. Staying hydrated is key to good health; as a constant companion, the Sigg bottle ensures a regular water supply for years to come, thanks to its particularly long lifespan. The sports bottle contains no harmful substances, including phthalates or estrogen-active substances. Made from high-quality 18/8 stainless steel, the water bottle is taste and odor neutral. All Sigg bottles are produced responsibly with the aim of reducing the use of single-use bottles.
