IceFlow™ 快流速蓋隨行杯 | 40 盎司

The 40 oz size means I genuinely go all day without refilling, which is perfect for long drives. The Fast Flow lid pours quickly without any messy splashing, and it’s held up fine tossed around my backseat.

The leak proof lid is a game changer for me—I tossed it in my gym bag with a half-full drink and not a single drop escaped. 40 ounces means I'm actually making it through my whole shift without hunting for a refill station.

Filled it with ice in the morning before a long drive, and twelve hours later there were still cubes clinking around—the 40 oz size means I barely had to stop for refills. The leak proof lid survived being tossed sideways in my passenger seat, which is more than I can say for my last tumbler.
