Two Drinks, One Cup, Endless Possibilities
Whether it's water and coffee, tea and lemonade, beer and soda, pre-workout and post-workout, or even a little something extra, Splitflask ensures that each sip is an experience worth savoring. No more juggling two water bottles—just pure, uninterrupted refreshment!
No More Juggling Multiple Drink Containers
The morning rush can be chaotic, especially when you're juggling your hot coffee and a refreshing cold drink for later.
Splitflask's dual-chamber design lets you carry both beverages in one sleek, easy-to-grab tumbler.
No more fumbling with multiple containers or making tough choices about which drink to bring—Splitflask simplifies your hydration routine, saving time and space while keeping you prepared for whatever the day brings.
SEPARATE INSULATED COMPARTMENTS
The water and coffee compartments are completely isolated and thermally insulated, ensuring that each drink maintains its ideal temperature without influencing the other.
This advanced insulation not only keeps your hot drinks hot and cold drinks cold for hours but also prevents any temperature transfer to the exterior of the tumbler.
With Splitflask, you can confidently carry both beverages without worrying about leaks, condensation, or compromised performance.

From the mind of a NICU Nurse ♥️
The idea for Splitflask came from a simple daily challenge I faced as a NICU nurse: I could only bring one drink container to work. This rule often forced me to choose between my morning coffee and staying hydrated with water throughout my shift. My husband noticed the trail of half-finished Starbucks lattes I’d leave in the car, and he realized the waste wasn’t just about the coffee—it was about having to choose between two essentials because of workplace rules.
Seeing my frustration, we envisioned a solution: a flask that could hold both hot and cold drinks at the same time. With this, I wouldn’t have to sacrifice my coffee for water or the other way around. That’s how Splitflask was born—a simple yet innovative answer to a problem many of us face, designed to make life just a little bit easier.
Frequently asked questions
Absolutely! Splitflask’s advanced double-walled vacuum insulation technology provides two separate thermal environments within one bottle. This ensures your iced tea stays perfectly chilled while your hot coffee remains deliciously warm for hours.
Absolutely. Splitflask fits in the majority of car cup holders.
Yes, Splitflask is dishwasher safe! You can conveniently place it in the dishwasher for easy cleaning without worrying about damaging its durable stainless steel construction or leak-proof seal.
We’ve built two unique features into the Splitflask DualSip lid to help you easily distinguish between the hot and cold sides:
- Clear See-Through Lid: The lid is made from transparent material, allowing you to see inside each chamber. You can typically identify the hot side by the condensation patterns—one side may appear foggy while the other remains clear.
- Dual Openings for Hot & Cold: The lid features two distinct openings—a flip-up straw for cold drinks and a flip-up spout for hot drinks. Simply check which one you’re using to instantly know whether you’re sipping something hot or cold.
