Our development team took up the challenge of creating the first (and only) 100% plastic-free Sport bottle on the market and only NonToxic Certified bottle on the planet. Our 100% medical grade silicone Big Mouth® sport top allows a free flow of liquids while eliminating the dreaded ice shift that often results in a soaked shirt or an embarrassing wet spot in your lap!
As with all bottles in the Pura offering, our 18oz bottle is 100% plastic-free and can be used with any of our silicone lids including our nipples, spouts, straws, and flat lids. With Pura you can rest assured that you are always using the safest and most eco-progressive bottle on the market.
