An insulated tumbler that won't spill or fall out of your hands. Wren designed it with a sliding lid and gasket seal for spill-free use, plus ridges around the body for extra grip. It'll keep your beverage of choice cold for eight hours, and hot for six. Take it on an evening hike, or slide it into your cup holder on the morning commute.
