Took this to the office and forgot about it until after lunch — ice was still clinking around in there. The insulated walls really do their job, way better than the cheap tumbler I used to carry.

Filled it with ice water before a 6am hike and there was still ice rattling around at noon. The lid seals tight enough that it hasn't leaked in my bag yet, which was my main worry with insulated tumblers.

Left it in a hot car all afternoon and my iced drink was still going strong hours later. The lid seals tight enough that it hasn't leaked in my bag once.
