You deserve options when it comes to hydration and that's why the Owala FreeSip Tumbler (40 oz.) stainless steel insulated tumbler was designed. 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 tumbler 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). Its 40 oz. size is completely leakproof and cupholder friendly.
