Lifefactory 22-ounce (650 ml) reusable glass water bottles offer a large capacity to quench a big thirst while providing an excellent alternative to disposable plastic bottles. These innovative bottles feature durable glass construction that offers pure taste. The bottle's glass is surrounded in a patented silicone sleeve that both protects against breakage and provides a comfortable, non-slip surface. The bottle also features a wide-mouth opening making it easy to fill with ice cubes, pieces of fruit, or drink mixes and powders. Meanwhile, the bottle's Flip Cap is perfect for use on the go. The medical grade, silicone flip top opens up and offers a controlled flow. The flip top seals when plugged but is not leak-proof, so please keep this bottle upright! The Flip Cap has a handy pivoting handle that makes it easy to carry the bottle and that stows out of the way while drinking. For easy care, the silicone sleeve and bottle can be washed together. All components of the bottle are dishwasher safe. It is recommended to wash the cap on the top rack. The cap is constructed of BPA/BPS-free polypropylene (PP#5) with no phthalates, PVC, or polycarbonates. The flip top is made of durable BPA/BPS-free silicone. All Lifefactory components are made in the USA or Europe and all products are assembled in the USA.
