This Travel Mug Lets You Alternate Between Sipping Cold Water and Hot Coffee

H2Joe, Kickstarter

You no longer have to choose between your health and your sanity when deciding what to drink in the morning. H2Joe, a water bottle-travel mug hybrid currently raising funds on Kickstarter, lets you drink water and coffee from the same bottle while keeping both liquids separate at their ideal temperatures all day.

Though it looks like a single container, H2Joe is really two vessels in one. The bottom portion is a double-walled, stainless steel travel mug designed for 12 ounces of hot coffee or tea. The top is the 12-ounce reusable water bottle. The H2Joe's triple-insulated design keeps water cool for up to eight hours at a time and the coffee hot for up to six hours, even when these liquids are stored just a few centimeters away from each other at vastly different temperatures.

The lid has one opening for each container: a spout with a screw cap for water and a flip top for hot liquids like coffee and tea. The lid and bottom mug twist off, making each vessel east to refill, and all the components are dishwasher-safe.

After launching a crowdfunding campaign on February 12, H2Joe reached its goal of $20,000 in just two hours. Hikers, commuters, and anyone else who's looking to consolidate the travel containers in their life have until March 15 to reserve a bottle on Kickstarter. H2Joe bottles are available for pledges of $36 or more, with shipping set for October 2019.
