This isn’t a better tumbler.
It’s a better solution. We didn't set out to make a cup that keeps ice frozen for 9 months. We made a cup that solves the "too many bottles" problem. Splitflask carries two drinks at once.
Use Cases

Built for the pairings people actually carry. Coffee and water. Pre-workout and hydration. Hot on one side, cold on the other.
