Zoe K. ★★★★★ Aug 9, 2026

The fast flow lid really does speed things up—I can chug without tilting my head back awkwardly, and the 50 oz capacity means I'm refilling way less during long workdays. Ice stays cold for hours, which is exactly what I needed for summer hikes.

The wide mouth on this lid is a game changer—I can chug water without tilting my head back awkwardly, and it still fits in my car's cup holder. Ice stayed cold for a full workday, which is exactly what I needed for my long shifts.

Filled it with ice in the morning and by evening there was still plenty left, which was a pleasant surprise for a bottle this big. The wide mouth opening makes it super easy to add fruit or just chug after a workout.
