Otso Klean Kanteen Insulated Tumbler
The custom branded Otso Tumbler was made by the great folks over at Klean Kanteen. The stainless steel Insulated Tumbler 16oz will quickly become your go-to cup, easily transitioning from morning coffee to afternoon smoothie to nighttime beer. The high performance double-wall vacuum insulation will keep drinks hot for 4 hours and iced for 20 hours. They electropolish the interior, a safe and non-toxic process, to make it easy to clean. The included Tumbler Lid keeps splashing to a minimum.
