Introducing the FreeSip water bottle, available in various sizes including a convenient 24 oz/ 32 oz/40 oz water bottle, a practical 32 oz water bottle, and a compact 24 oz water bottle. You deserve options when it comes to hydration and that's why we designed the FreeSip to let you choose your own adventure—hold upright to sip through the built-in straw or tilt back to swig through the wide-mouth opening. If that isn’t exciting enough, this bottle is ready to spring into action at any time. Just push the button to flip the top open and push back down to lock it shut . But we should warn you: If you’re one of those people who likes bottles that spill water everywhere, the FreeSip is completely leak proof.
