Era Flip 20oz | Guava

This tumbler trades the exposed straw of most insulated cups for a flip-down cover that keeps the mouthpiece clean and locks tight enough to toss in a bag without worry. The straw itself is a hybrid: silicone at the top for a soft feel on your lips, metal inside to reduce contact with plastic. A push-button latch releases the lid, and when you snap it shut the seal holds against leaks even with carbonated drinks inside.

Double-wall vacuum insulation keeps cold drinks cold for more than a day, so you can fill it in the morning and still have ice after dinner. The 20-ounce capacity fits most car cup holders without the bulk of larger tumblers, and the stainless steel body stands up to daily use without sweating onto your desk or console.

The straw sits covered until you need it, which matters if you keep the tumbler in a gym bag, backpack, or anywhere dust and debris can settle. When the lid is locked, the tumbler is fully sealed—no drips, no splashes, even if it tips over. BruMate recommends a fifty-fifty ice-to-liquid ratio for carbonated beverages and advises against locking the lid with hot drinks, which can build pressure.

Every piece disassembles for cleaning, and the wide mouth makes it easy to add ice or scrub the inside. The silicone straw tip is smooth enough for comfortable all-day sipping, and the metal lower section keeps plastic away from prolonged contact with your drink. Whether you're commuting, running errands, or working through the afternoon, this tumbler stays sealed until you open it and keeps your drink at the temperature you started with.
