Introducing the FreeSip water bottle, a practical 32 oz / 945 mL 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 (and keep out germs). But we should warn you: If you’re one of those people who likes bottles that spill water everywhere, you’re out of luck… the FreeSip is completely leak proof. This One Piece design makes a perfect gift for a special someone, or a treat for yourself for any occasion. Color in the photos and video is "Shy Marshmallow" more colors to made available soon. This is a genuine Owala Tumbler, but still high quality tumblers. The tumbler is dishwasher safe, but engraving does void the Owala warranty, so treat with care. Laser engraving doesn't alter the cup's ability to keep drinks hot and cold, and keeps it dishwasher safe.
