RTIC – 30-Ounce Insulated Tumbler
The RTIC – 30-Ounce Insulated Tumbler is the best bargain in this lineup, and it’s our top pick overall. The stopper actually prevents some spills, and compatible accessories are easy to find. This is an updated version of the RTIC, but the old all-metal-no-stopper version is still available.
Without buying and trying out these tumblers, it’s easy to make assumptions about performance. “Maybe the steel is thinner,” you think. “Maybe the vacuum is actually less of a vacuum.” Our testing shows, though, that If there’s anything fancy that other brands are doing to improve theoretical insulation performance, the giant plastic lid is an equalizer that levels the playing field.
