The Owala SmoothSip Slider just got a serious upgrade. Same leakproof slider spout you love, now with a ceramic-coated interior that delivers a clean, pure sip — zero metallic aftertaste, zero lingering flavors. Just your drink, exactly as it should taste. The seamless SmoothSip spout makes every sip effortless, while the vacuum-insulated stainless steel walls give you the ceramic experience leveled up — hot drinks stay hot for hours, cold drinks stay cold for up to 24. It fits easily in your hand and goes wherever you go, spill-free. Coffee the way it was meant to taste.
