Not all tumblers are the same. Take our Bison 22 oz. tumbler for example: we used some of the thickest stainless steel on the market to build it because we wanted a strong, drop-resistant tumbler that you could use for years. Vacuum-insulated construction keeps liquids cold for 12 hours and hot for up to 6.
