Leak-proof and sustainable. The Sigg Shield One drinking bottle is the ideal companion for all leisure activities, 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 makes the drinking bottle easy to use with one hand: this applies to carrying, opening, drinking, closing and securing the bottle. The leak-proof drinking bottle is also suitable for carbonated drinks. The extra-large opening helps when cleaning and filling the bottle, so that even ice cubes fit into the bottle. Drinking enough water is the key to good health; as a constant companion, the Sigg bottle ensures a regular supply of water - for years to come, as it has a particularly long service life. The sports bottle does not contain any harmful substances - including phthalates or oestrogen-active substances. Thanks to the high-quality 18/8 stainless steel, the water bottle is neutral in taste and odour. All Sigg bottles are produced responsibly with the aim of reducing the use of disposable bottles.
