Stainless Steel Insulated Tumbler Cup with Straw & Sip Lid

Key Features

• STOP CARRYING TWO DRINKS EVERYWHERE: Coffee in one hand. Water in the other. Splitflask puts both in one cup—so you can stop juggling and just go.
• TWO COMPLETELY SEPARATE DRINKS: Dual chambers keep your drinks separate—hot and cold at the same time, no flavor crossover when the lid is aligned correctly.
• BUILT FOR REAL-LIFE USE (NOT A THERMOS REPLACEMENT): Splitflask is designed for convenience—carrying two drinks at once. Both drinks stay usable for your commute, workout, or daily routine.
• TAKES 1–2 USES TO MASTER: The lid must align with the center divider to seal both sides properly. Once you get it, it’s simple.
• BUILT FOR YOUR DAILY ROUTINE: Fits most cup holders | Dishwasher safe | Comfortable grip | One cup instead of two.
• EASY TO USE AND CLEAN: 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.
• WHY IT'S A BIT HEAVY: 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.
