Trek 隨行杯

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.

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.
