Avery ★★★★★ Oct 20, 2026

I’ve been refilling this tumbler way less often because the 50oz capacity actually lasts me through my whole workday. The straw lid seals tight enough that I can toss it in my bag without worrying about leaks.

Leo ★★★★★ Oct 19, 2026

The double-wall insulation really works—my iced coffee still had ice chunks after six hours in the sun. The 50oz capacity means I only have to fill it once for my whole workday, and the straw lid hasn’t leaked once in my bag.

I was getting tired of refilling my water bottle every hour, but this 50oz tumbler truly keeps me going all day without a trip to the tap. The double wall insulation actually works—ice was still there after an afternoon in the car.
