Split Cups

Two drinks. One split cup.

A split cup is a drink cup divided into two sealed sides, so you can carry two drinks in one cup without them mixing. Splitflask is a patented 2-in-1 dual chamber tumbler with two separate 15oz chambers (30oz total). Carry hot coffee on one side and cold water on the other, or fill both with water.

• Two sealed 15oz sides: coffee and water, two different drinks, or 30oz of water.
• Independent vacuum insulation: the divided stainless steel interior limits temperature transfer between chambers.
• Food-grade 18/8 stainless steel with secure, leak-resistant seals when both lids are closed correctly.
• Cup-holder friendly: one cup instead of juggling two bottles or travel mugs.
