I can’t speak for others, but my beverage preferences call for somewhat extreme temperatures. If you are just like me and need both a hot beverage and ice-cold water throughout the day, then you know the hassle of carrying two separate bottles. Fortunately, someone has thought about people like us and introduced Splitflask 40 oz. tumbler that lets you carry two drinks – at their different temperatures – simultaneously.

This is possible courtesy of the Splitflask’s dual-chamber design. Thanks to patent-pending technology, the two chambers are completely independent, meaning you can enjoy hot drinks and cold drinks without them affecting each other or having to carry two separate flasks. I know you might have questions. Does it leak? Do the two drinks get mixed? The answer is: no, sir.

This tumbler boasts a leakproof construction that allows you to carry the dual-drink container in your purse, gym bag, or backpack without worrying about spills. That’s a big relief for me as I generally end up tossing my loosely-closed flask in the bag, only for it to leak and wet the contents. No wonder my boss calls me a ‘clumsy ninja.’

Since the tumbler lets you carry two drinks at once in two separate sections, your coffee remains piping hot and your water refreshingly cold throughout the day. On top of that, the Splitflask’s high-quality insulation ensures your drinks maintain the perfect temperature for hours. That’s something I like, given the approaching summer.

To summarise, the dual-drink tumbler is designed to adapt to your needs. Whether you’re commuting to work or hitting the gym, the tumbler is perfect for on-the-go use. Complementing the functionality is the sleek design and the array of colours (pink, green, black, and white).

The tumbler is currently crowdfunding on Kickstarter, and you can snag it for a super early bird price of $49. The company has its 40 oz. prototypes ready and is eyeing to begin deliveries in August.
