We tested 20oz tumblers to determine which work the best. We compared the YETI, Ozark Trail, RTIC and a generic tumbler. We had one twist. The Ozark Trail was equipped with a StopIt LocTop. The YETI, Ozark Trail and RTIC are a stainless steel double wall design with a vacuum pulled between the walls. The generic is a stainless steel/plastic double wall design with air between the walls.
For data collected with and without the StopIt see StopItTop.com
The StopIt is Patent Pending.
