Lifefactory creates innovative, non-toxic products that make it easy to lead a healthy and eco-conscious lifestyle. They fuse modern sensibility and exceptional utility to produce a glass beverage bottle that is free of known harmful chemicals such as BPA, phthalate, PVC, and polycarbonate. All materials are FDA approved. The unique silicone sleeve is free of plastics, 100-percent non-toxic, provides a great gripping surface and helps prevent breakage. The benefit of using a glass beverage bottle is that there is no risk of chemicals leaching into your drink and no metallic taste. The flip top cap has a narrow mouth spout for easy on-the-go drinking. And the wide mouth bottle makes it easy to add ice, citrus slices and tea bags. Beverage bottles are easy to clean and dishwasher safe (the glass bottle and silicone sleeve can also be washed together in the dishwasher). Leakproof Flip Top Caps are compatible with all 16-ounce and 22-ounce Lifefactory bottles. Each bottle holds 16 ounces (450ml). All components made in the U.S. and Europe.
