The VIVA ONE bottles are made for active lives spent everywhere, not just at home! You can always see how much youve already drunk. And the innovative ONE cap also makes the bottle extremely comfortable: Carry, open, drink, close and seal all conveniently with one hand! The high-quality, recyclable drinking bottle is made from transparent polypropylene. All materials are 100% recyclable and free from harmful chemicals, such as oestrogen-mimicking substances and phthalates- for safer drinking enjoyment.
