Ice stayed solid in this thing through a full day of errands and a hot car, which honestly surprised me. The insulated wall really does what it claims, and the tumbler itself feels sturdy without being heavy to carry around.

Filled it with cold brew at 7am and there was still ice clinking around at 4pm, which I did not expect from a tumbler this slim. The lid seals tight enough that it hasn't leaked in my bag yet.

Ice stayed in my cup all day through three refills, which never happens with my old tumbler. The lid seals tight enough that I can toss it in my bag without worrying.
