It’s the only dual-chamber tumbler built to actually work for real people with real routines, hot + cold cravings, and chaotic schedules.
🗣️ “I used to balance a coffee cup and water bottle on my commute. Now it’s all in one cup, and I’ll never go back.” – Sarah M.
BEVERAGE CLUTTER WON'T FIX ITSELF
Carrying two bottles everywhere leads to a bag full of chaos and a desk that looks like a hydration graveyard:

- Spills, leaks, and sticky desks
- Never enough room in your bag
🗣️ “I had no idea how much of a hassle my drink setup was until I switched to Splitflask. Total game-changer.” – Emily R., 29

Frequently asked questions
Does it leak?
Nope. The lid is 100% leakproof when closed—tested in gym bags, cars, and tote bags.
Will both sides mix?
No. Once applied properly, the lid effectively seals both chambers, preventing your drinks from mixing.
How long does it keep drinks hot or cold?
Splitflask is designed to carry two drinks–2 hot drinks for up to two hours or 2 cold for up to 4 hours. If you want to carry hot and cold drinks at the same time, you will get about 1-2 hours for each temperature.
When will I get my order?
We will work quickly to ship your order as soon as possible within 24-48 hours. Once your order has shipped, you will receive an email with further information. Delivery times takes 2-5 days depending on your location.
Is it dishwasher safe?
Yes! The entire tumbler is top-rack dishwasher safe.
Can I put coffee and water together?
Absolutely. They’ll never mix—unless you want them to.
How much does shipping cost?
Shipping is calculated based on your location and the items in your order. You will always know the shipping price before you purchase.
