Took this to the beach on a 90-degree day and my drink was still ice-cold six hours later. The lid seals tight enough that it didn't leak in my bag, which honestly surprised me for a tumbler this size.

Filled this with ice water before a hike and there was still ice rattling around six hours later. The lid seals tight enough that it hasn't leaked in my bag once.

Kept my water cold through a whole afternoon hike, which is honestly more than my old tumbler managed. Only gripe is it's a bit heavy once it's full, so it's not the one I grab for a quick walk.
