The 0.75-liter size ensures you always have enough water at hand while drinking a little at the computer for instance. And it is spill-proof. Thanks to the innovative ONE cap with the extra-large WMB opening, it’s extremely comfortable to use: Carry, open, drink, close and seal conveniently with one hand – plus filling and cleaning the bottle is child’s play. Even ice cubes fit in this SIGG. It’s made from featherweight, durable Tritan that’s taste and odour-neutral. Naturally free from harmful chemicals, such as estrogen-mimicking substances and phthalates for safer drinking enjoyment.
