Voyager Tumbler met doorzichtige flipdop en rietje

I was surprised how long my iced coffee stayed cold — ice cubes were still floating after four hours in the car. The straws work smoothly with the flip lid, and the cup fits perfectly in my car's cupholder.

The flip lid twists on tight enough that I tossed it in my bag without a drop, and the two straws mean I always have a clean one ready. Ice cubes were still clinking around six hours later, which honestly surprised me for a tumbler this size.

The double-wall insulation really works—my iced coffee still had ice chunks after four hours in the car. The twist-on lid seals tight enough to toss in my bag without a single drop escaping, and having two straws means I always have a spare.
