About This

• Kid side + mom side (no backwash): Kids always want a sip. Give kids their own side for juice or water while keeping your coffee or Iced Tea untouched. They feel included; you stay backwash-free.
• Two Drinks, One Leak-Resistant Tumbler: Carry coffee + water, pre + post-workout, or kid drink + mom drink in one 30oz dual-chamber stainless tumbler. Two 15oz sides stay fully separate when the lid is aligned.
• Real-World Hot & Cold Performance: Hot stays warm 1–2 hours, cold stays chilled for hours. Cold + cold lasts even longer. Perfect for commuters, parents, teachers, nurses, and gym-goers who refill throughout the day.
• No Mixing, Separate Chambers: Each side has its own seal and channel. When the lid is aligned with the center divider and cups aren’t overfilled, drinks stay fully separated and the tumbler stays leak-resistant.
• Built for Everyday Life: Dishwasher safe, BPA/BPS-free, non-slip base, 18/8 stainless steel, labeled sides, straw + sip openings, and fits most car cup holders. Heavy-duty by design.
• Simple once you know the trick: Fill cold first, then hot. Don’t overfill. Align the lid’s center strip with the inner divider, press down, and quarter-turn to lock. All parts and gaskets come apart for thorough cleaning.
• Weight: Splitflask uses double walls + dual chambers, so it has a bit more heft than a standard tumbler — that’s the tradeoff for carrying hot and cold at once.
