Enjoy ice-cold sparkling drinks that start fizzy and stay fizzy* with Ninja’s first carbonated drink travel bottle. It's perfect for fizzy drinks, water, tea, coffee and more. Triple Thermo Insulation Carbonated drinks can quickly lose their fizz. Thanks to BubbleLock technology, a super-polished interior offers fewer nucleation points which can cause bubbles to escape, turning your drink flat. This means you can enjoy drinks that sparkle for longer with each sip. And thanks to three layers of vacuum-insulated stainless steel, you can expect ice that stays frozen for two days, hot drinks that stay piping hot for eight hours and cold drinks for 24+ hours. LockLeak Technology A tough BPA-free plastic lid prevents spills, leaks and drips, no matter what your day has in store. The lid keeps your drink sealed in, with a rubber gasket and sturdy mechanism for extra protection. Made for comfort and portability Ninja’s engineers have created a travel bottle built for optimum performance and comfort. The smooth, round spout allows you to drink comfortably – whether you need a quick sip or big gulp. The lid even snaps into place to ensure it won’t move as you drink – perfect for taking a quick one-handed sip during a jogging or workout session. Two grooves on either side of the bottle also offer extra grip for wet hands. The triple insulated layer ensures you can hold the bottle comfortably, no matter how hot your drink is. *Lab-tested using commercial carbonated beverages, ensuring a minimum carbonation of 2.5g/l is maintained throughout the testing duration.
