Stella ★★★★★ Oct 20, 2026

I've been using this 50oz tumbler for a week now and the double wall insulation really keeps my coffee hot for hours. The large capacity means I only need to fill it up once during my work day.

Steven T. ★★★★★ Oct 19, 2026

The straw lid snaps shut tight enough that I’ve tossed it in my work bag with coffee inside and not a single drop escaped. Fifty ounces means I’m only refilling once a day, which is honestly the best part of my morning routine.

Filled with ice at 7 AM and it was still chilly at lunchtime — the double wall insulation really delivers. The 50oz capacity means I’m not running for refills every hour, which is perfect for my long hikes.
