Absolutely, both compartments of the Splitflask can be used for either hot or cold beverages—they are completely interchangeable and perform equally well for both.
Each side is independently vacuum-insulated to prevent temperature loss or gain from either side. So you can carry:
- A hot beverage in both chambers,
- A cold beverage in both chambers,
- A hot beverage in one chamber and a cold beverage in the other chamber.
Hot stays hot and cold stays cold.
Absolutely! Splitflask's innovative double-walled vacuum insulation creates separate thermal environments for each chamber, ensuring your iced tea stays refreshingly chilly while your hot cocoa remains comfortably warm for hours.
Splitflask is designed with two 15oz chambers for a total of 30oz.
Each side of the Splitflask water bottle can hold up to 15 ounces of liquid for a combined total of 30 ounces.
No. Our Dual-Sip™ lid is spill-proof and mix-proof, ensuring that both beverages stay out until you are ready to enjoy them independently.
Splitflask stainless steel water bottles is dishwasher safe. However, hand-washing is recommended to ensure a longer lifespan and optimal performance of any stainless steel water bottle. If using dishwasher, be sure to place it in the top rack of your dishwasher and not the bottom.
Yes. Splitflask is BPA and BPS-free.
You can purchase replacement straws, lids, and other accessories from our store.
If you have a damaged straw cover or spout cover, please email us at hello@splitflask.com for a replacement part.
Yes. Splitflask will fit in your car’s cup holder.
The 40oz version does but the 30oz version not. In order to preserve the minimal design aesthetic, Splitflask 30oz does not come with a handle. However, we have developed a removable handle attachment accessory which will be available for purchase soon.
You bet! The Splitflak insulated tumbler's leakproof lids prevent any embarrassing beverage mishaps in your bag, backpack or car. We designed a no-spill, no-mix, no-stress tumbler lid.
While hand-washing is always recommended, most Splitflask insulated water bottles are dishwasher-safe. Simply remove the lids and any detachable components before placing them in the top rack of our dishwasher. If hand-washing, simply soak in warm soapy water and sue a soft bristle sponge to scrub and rinse thoroughly afterwards.
Make sure the middle strip of silicone at the bottom of your lid is perfectly lined up with the middle stainless steel divider in the cup. This will create a perfect seal between each chamber and prevent temperature transfer, allowing the temperature in each chamber to last longer.

This is typically due to some residual liquid on the exterior of your lid, trapped in the nooks and crannies of the straw and spout flaps. Make sure the exterior of your lid is wiped and dry.
Also make sure you have a perfect seal by aligning l the middle strip of silicone at the bottom of your lid perfectly with the middle stainless steel divider in the cup. This will also prevent temperature transfer between chambers, allowing the temperature in each chamber to last longer.

Yes. Unlike many other cups in the market, we knew a water bottle that spilled was a dealbreaker for our discerning customers. So we designed a no-spill and no-mix Dual-Sip™ lid.
